Amount of CFM available from 452 heads, heavily ported

I think @IQ52 (Jim Laroy) has made 700 plus HP from 452s fully ported. Maybe he'll chime in.
452's on the 451 pump gas stroker was 650+ hp and 906's on the 500 pump gas stroker was 730+ hp. Both sets had 2.25/1.81 valves.

Just for the fun of it let us add that ported Edelbrock RPM heads made 787 HP on the same 451 pump gas stroker. Yeah everybody got 2.25 intakes.
