hey guys is there any heads that can be swapped on a 2.2 ecotec? or whats the best build for the head? is it worth you think? I just am looking for some ideas

patriot stage 1 or 2 heard or send a spare head off to a company MR2 or something and have them port and polish



LE61T PTE6262 Powered

if I am going to spend $3000 into the motor and want to keep it n/a. what recommendations do you guys have?

someone will be able to tell u the exact parts, but for 3000 i figure u could prolly pretty much literally rebuild the engine from the ground up with performance parts, ud have a nice lookin engine

M2Race, Phil.

My personal head build for my eco is going to be a M2Race ported L61 head with .5mm GMR valves, 94lb Supertech valve springs, and comp blower grind cams.

no one likes the gmpp head thats based off the lsj casting (with already bigger ports and tons more material for a proper porting job)?

As i recall you can port the L61 head almost as much as the LSJ head. As for my choosing the L61, it was simple, i already have a spare complete L61 with 15k on it.

LSJ exhaust ports.. much more meat for port jobs


L61 has very large holes directly beneath the #2 and #3 cylinders so port jobs have to be done carefully, and more conservaitvely.

lsj has sodium filled valves, better for boost.

the valvetrain otherwise is the same across all variants.



port the head you have, send it to www.M2race.com
0.5mm oversized on the valves, stainless intake and inconel exhaust valves, 94lbs. springs are identical to the ones GMRacing uses.

the GMR stuff is more expensive than Supertech, but the specs as far as springs go are similar.
a lot of people are having luck with supertech springs and valves, but if you have the cash, go with GMR.


the patriot head isn't worth the money, it barely flows anything more than stock.. the M2R head flow numbers are a lot better, and at usable lift to (ie. less than .450)

I had my lsj head done at m2 race great work and customer service and they can do an l61 head they might have one done they can sell you.

what kind of power gain are you getting from doing this work? my goal is 250 hp on a n/a

I have no dyno sheets i can tell you it feels alot stronger. They did a dyno on a cobalt with exhaust and this head and made 50hp i just dont know how accurate that is.
