Hey guys, It's been a long time since I posted. I was taking my lower intake off to put a ported lower on. Once I got the intake off, I think it's the number 1 and 5 cylinders (the two front) the runners on the heads were half covered with the lower intake gasket. It looked melted. What would cause this? Do you think the two front cylinders are running lean? I have stock fuel rails, I also do not have the car tuned. I'm getting it tuned soon. Thanks for any ideas.
