ok, a friend of mine is always throwing around statements about these 2.02" chevy heads like its the best way to go for a high performance engine. He tels me that an engine likes to "breathe". Long story short. The engine he would build would not be in a race car but in a daily driver on pump gas.
My arguement to him is, if the engine is not turning high rpm's he would have more power and useable tourque with a set of heads that had much smaller intake valves. Please corect me if I am wrong, but it is my belief that the velocity of the air fuel mix has a huge role in how an engine runs, and having the biggest heads and cam in a 350ci engine does not always mean its the way to go. Besides, we live at a high altitude and the roads are so crooked you could never really open up the throtle for long anyway.
So in a nut shell, I say 1.78" or no bigger than the 1.94" would be better.
Can anyone help settle the debate?
