Again, obviously you didn't do it right, a smaller head will never "flow" what a bigger head will when ported CORRECTLY lol. I sure see allot of over achievers at the track with "big" heads and "small" cams, wonder what's up with that?. I mean if you want to take small heads and cam them to oblivion to try to do the same thing be my guest but don't try to convince me that's more efficient.
