Reply to "aluminum heads"

My unported A3's were quite good on the flow bench, better than the
CHI 3V heads in terms of raw flow numbers but that's not an apples
to apples comparison because of the A3's larger ports. My C302B
heads were essentially the same port volumes and were better than
the A3's or the CHI 3V's.

Dan isn't this statement contradictory?
If the C3 has been ported to the same volume as an A3 port, then for all intents and purposes it is an A3 port isn't it?
The only thing the porter could have possibly have done was straiten the runner and play with the short radius?
It is the cross sectional area of the port that effects the port velocity. The length of the port couldn't have been changed, and the volume is the same, if it walks like a duck...it's a duck.
