That's an impossible question to answer. It all depends on your engine, cam and exhaust- not to mention if you're using some sort of forced induction. Then you get into the bare heads vs. CNC bowls vs. full CNC porting vs. CNC/hand-worked porting.

There are a gazillion variables and when you move one piece, the others change.

Heres some good reading material about your question
