I agree on the velocity thing 100%. Hughes Engines used to advertise their head porting that way yrs back. Dom uses ported Rpm heads on a 470 and i use E MW heads on a 511. Doms engine makes more power than my 511. Compression is not much different between the 2. I think my 511 combo may make more power with RPM heads.
Mine may be considered max ported base on Pettis and George Koopals opinions but no flow #`s since I was in a hurry to assemble and the flow bench was tied up. I know that on a chassis dyno years ago it was still makin power to 7000 where I stopped and went home and on the street, it's a beast to me anyhow w/a new best hopefully very soon..........I plan on a max wedge build next year and a bigger cam..............
