Alright. I did some searching on intake manifolds. and cleaning them I was just curious as to opinions on how clean or dirty is my ports on my head. Is it normal carbon build up or is it pretty dirty? The reason why I am asking this is when I purchased this car the person prior to me was running the vehicle without an air filter. I'm unsure how long he had been running it without the air filter, but my guess is probably longer than he should have been especially in my area with the amount of dirt roads I know the guy had been on and racing on. Here is some pics. just so you can see what i'm talking about.
