Re: air flow ?
Ok lets map the head flow onto the cam lift curve.Flow @ .500" 200, @ .550" 200.5 @ .600 210
The cam is a Lunati that has .507" lift with 1.5:1 rocker arms (green line) and .541 lift with 1.6:1 rocker arms {blue line) and .575" lift with 1.7: rocker arms (magenta line)

PS - Let me add a little more explanation. I have the ICL set at 110. If the engine is a 350 ci sbc (4 x 3.48 x 5.7) the peak piston velocity will be @ 74.3 ATDC which is also point of peak piston flow demand. Now as RPM goes up there will be a small delay seen at the intake. But you can see how as lift has increased the flow at peak demand has also.
