defently a improvement over stock flow, but you should take the next step. Polish it up, or try to get it smoother.

I agree it is a start, but you REALLY need to flowbench the head in order to get the best numbers.

Yeah that's my g/f's rug. Ugly thing I think lol... yeah I started to chew through sandin rolls and ran out during polishing especially since I am very picky I am tryin to get the best flow with my product especially since I am catchin so much heat for doing this from fellow j body members.
So let me know your guys opinion
Devon doesn't look bad at all for $200.

Your pictures totally confirm my previous statements....
Toaster (stenger), just because the holes are bigger does NOT mean it will flow better. If Devon's "scuff job" does not pay attention to simple physics, turbulance will impede flow.
Going through the pictures one by one:
1. The casting marks are still present in areas suggesting a "scuff job" was performed. There's a major lip where the intake port meets the injector hole. This will cause unwanted turbulance. Note the thickness of the port divider between the two valve races (I will bring this up shortly).
2. The same port as picture 1 so no need to repeat.
3. Not much to talk about here other than the fact that casting marks are still visible on the lip of the port. This suggests no port matching to the gasket was performed.
4 & 5. Hot tank your damn head before you start a port job. Also don't think you can reuse those valve guide seals at this point. There's probably tons of metal shavings caked up in them from your work. These pictures show carbon deposits on the mating surface of the exhaust flange. This means you didn't port match the ports to the gasket. Have a look at the knifed port dividers between the valve races. Are they identical? Absolutely not. I bet you $1,000,000 that when you go to flowbench your work, NONE of the ports will be identical in flow.
6. Not much to talk about here.
7. Casting marks are still present. Swirl marks are somewhat visible (this is good) which will aid in eddy currents.
8. You really dropped the ball here. The exhaust ports should be as smooth as glass. Scuff marks will really hinder flow on the exhaust side and will produce hot spots for the extremely high temperature gasses that will be expelled from those ports. Polish the bowl!!!!
9, 10, & 11. Again, MAJOR inconsistency between the knifed dividers. Carbon deposits are very visible and show that no port to gasket matching was performed.
12 & 13. Knifing the dividers on the intake ports is a VERY BAD thing to do. Over time, heating up of the head will cause the thin area of the divider to crack off and get sucked into the engine which will potentially cause damage to the cylinder wall, piston, bowl, and valves as it's knocked around before being spit out. If this head is going on a turbocharged engine, that piece of metal will also smack the blades of your turbine spinning in upwards of 100,000 rpms. Not good at all...
14 & 15. Why did you even bother touching the compression knotch in the bowl if you didn't intend on finishing the job by doing the whole bowl? Based on the perspective of picture 14, you've created a point of detonation on the knotch. Not good.
Devon, I'm really not trying to give you a hard time. However, if you expect to sell this type of work to JBO, you're asking for a whole world of legal hurt. This is not quality work what-so-ever and has the potential to destroy an engine in a couple different ways. What if you sold this head to someone, the knifed divider cracked, fell into their engine, destroyed one of the cylinder walls, shot out of the exhaust port, and toasted the wheel of their turbocharger's turbine? Eventually, the rings would fail on that piston, compression would be compromised, and total failure would be imminent. Once the engine was torn down and inspected, it would be pretty obvious as to the cause. At that point, if I were that person, I would flat out sue you for the destruction of my engine. Why? I've got nothing else to lose at that point since it was all taken away from me by paying for a lousy $200 port job...

Funny the head for my 3800 that were ported the same way work just fine and a supercharger creates a @!#$ load of heat into a motor. But whatever and like I said this is the beginning I just ported to the stock gasket size cause I would need someone to send the gaskets they are using to port to match and ummm yeah I know that the knife edging is dangerous bud that's why like I said IT'S THE BEGINNING.... like I asked I wanted your opinions. So thanks for the opinion.
For those who trust me you can let me know for those who don't then I wish you luck in your motor build
since we're on the topic of porting, would you recommend port matching the 2.3L HO manifold to the 2.3L LD9 head? Because i hear that there would have to be some sort of metal added to the bottom of the port for it to match properly.
I am still gung-ho for the adapter flange, but i was just curious.

As I stated in my previous post in the previous thread. All you are doing is gasket matching and now that I see the pictures I wouldn't even call it a gasket match. I laugh at anyone who would pay $200.00 for this kind of work, anyone could do it in a weekend in their own garage. Like I said before you have allot to learn about porting and Mr. Pute has hit the nail on the head with his post.

I didn't say it was perfect now did I Pute?
But if your going to do it, do it right. Flow bench, and smooth out the intake side of things. Shouldn't be able to see where you worked. There's like ridges.
And don't polish too much on the intake side, because that will screw up the air/fuel delivery.
Porting heads isn't as easy as it sounds. A lot of attention to detail goes into it. Just keep that in mind.

Thanks toaster I will. Its hard work man tryin to do everything.... but I will.
And I just started bud and harrington I would laugh at anyone who would take advice from you... I told you to take it on the streets against a grocery getter that has some ported heads the same way these are and I haven't heard anything so obviously you talk a lot but I don't see much action. Or you can just go against my car after winter that will have the same port job too... so what's it goin to be? Harrington? Harrington?.... what's it gonna be?
Any other opinions let me know
Heres a few quick tips, Im doing my own head right now:
1) dont knife edge on the intake side.
2) Polish the exhaust bowls and ports
3) Leave the intake side rough, but uniform.
4)Polish your combustion chambers, but dont remove any material (you'll lower your compression)
5) It only costs like 40 bucks to get a head bead blasted at a machine shop, its alot easier to work on a clean head.
Another thing, if you are doing a home port job and youre not going to flow bench your work dont remove a huge amount of material. Gasket match and blend an inch in and then just smooth and polish everything. If you are not removing huge amounts of material you really dont need to flow bench anything.

keep at it devon...least you got some good constructive help! Mr Pute knows his stuff, I'll back him
You get a thumbs up from him...I'll have ya do one for me

Dude you are a complete jack a$$. Why would I want to drive to another state to street race some snot nose kid who thinks he knows it all? Do you actually think you are worth any of my time? Dude your port job is a joke and your mad cause I told you it sucked. The last thread you were all "you don't know who your messin with" give me a break kid i @!#$ bigger than you. Now your all "whats it gonna be" like you intimidate me or something. You ask for opinions and I gave mine so STFU. If you can't handle the truth then don't ask for opinions.

Harrrington I am not trying to be a dick by far but you are a lil harsh in your ways of talkin to people which piss people off. And quite frankly I really don't care about what you have to say about anything. Now mr. Pute is constructive comments, your just a dick head. Pretty much.
Guys I know that these heads are not like the best! But once again I am not the best either. But I do have a lot of help and good people who also know their stuff as well that is why I ask for opinions. Not to get @!#$ted on by some members in here that call me a dumb ass and stuff like that.
I didn't call you a dumb ass I called you a jack ass, get it straight.

Ok now your just a dick head
Why cause your a dumb ass kid who thinks they know somethin, tryin to rip people off for $200.00 with the worst port job I have ever seen. I called you out on it and now your mad because I exposed how crappy your work is. Sounds to me like your the dick head.

No I am tryin to do service so that people can actually build motors and not pay a fortune I didn't say that I didn't have a lot to learn but I do have good help here in columbus ohio too. Idk why you think you think that you can talk to people the way you do and think that they won't get a lil upset... I have tried to keep a level head with you but quite frankly you are just pissin me off. I didn't say I was the best because if I was the best I would be ummm charging you guys like a 1000 bucks because then it would be a lot better quality of work. Practice makes perfect and good constructive opinions make you better not some jack ass that just @!#$s on people's work when they admitted that they just learned and asked for opinions....
Like I said before harrington since your the best at everything and love degrading people why don't you come over this winter and help me put together my car?????
I have no problem with mr.pute's comments at all because it is constructive opinions yours is just you being a dick head. So if you don't mind you can take out your anger and opinions somewhere else cause quite frankly I don't give a damn what you have to say really.....
And if I was tryin to rip off people I wouldn't of posted pics at all or asked opinions so you can shove that somewhere. I have helped a lot of j-body members out and have given up my time to help them work on their cars for free! So I by far don't rip people off.... CASE CLOSED

what did the guy ever do to you? I think what he is doing is good on his behalf, as this is one of the ways of starting a full business. to me, what he is doing, as he is still new at it, is a "build at own risk" kinda thing. like @!#$, all anyone ever wants is people with alot of experience these days, well, how do you get people with experience if you don't start from the begining. I say congrats to the guy for even starting this up and having the balls to post something like this up for the constructive critisism by mr. pute and other members who are willing to help out. for the love of god, re-read what you put and just try to say you didn't think you were being rude about it.
you make me, and possibly others, think you are one of those self rightious @!#$ faces who think they know everything, seems to me like you have alot more to learn.
just to barge in for a moment Devon isnt a kid..... keep practicing, eventually you will learn how to do it perfectly..
