I went over and read that and I don't think I disagree with what was said. The big port heads will make tremendous power at at low rpms and through the full rpm range especially at full throttle. The problem is smooth transition from part throttle to full and back or smooth running at any position without flat spots. I have run big port heads on the street but I don't think I gained drivability. That's why I say if you can get the big head for the future it may be a good idea. If I passed someone it wasn't that Fox guy, he knows his stuff!
