Can't say for certain, on a AMC 1970 and later heads, if you touch the floor of the port, it will flow worse. It was designed to have that ramp on the floor of the port on AMCs. May be the same on our engines as they may have the shape there for a reason. Bench flowing for the correct porting would be expensive. RX may have just ported the heads and put it on a dyno without flow testing. That is just a guess. I will say that Tracy took three calls from to help me with questions regarding changing out the timing chains on my Camaro. Even went out and put a mechanic on the phone for chain alignments.
