Section 8 said:Don't let yourself get sucked into the numbers game. A flow bench is good for seeing how easy, and how much air can flow through an orafice. An intake port that can flow 1,100 CFM will not be a good choice for our little engines. But that doesn't mean that a smaller intake port is better either. After a little porting and polishing, normal heads generally have the best all around performance. Its when you start hogging out the heads that you start to loose low end and increase the high end. Its all about the tune which heads will be the best choice for which cams at which RPM. Your heads might perform worse with stock cams than the stock heads. When its all put together, the only thing I care about is the intregral power. Flow bench numbers are nice to see what you did before you put it on the engine, but they don't tell anybody about what charecteristics you brought out of the heads, and peak HP is something to tell someone who doesn't know much about cars, so you don't have to explain a whole lot to them.
