Build me a 800hp NA 512 b block using pump gas

Thank you again IQ52. Now...to sound really stupid here. The first article you sent showed a 451 with ported RPM heads (349@800) making 770hp on pump gas. You said the Victor heads were troublesome. Here's a thought that might seem stupid but I have to ask. I keep seeing you guys talking about the Trick Flow heads and how well they flow OOTB compared to RPM's. If they flow 332 @ 700 with out porting I'm thinking they should possibly be able to be ported enough to surpass the 349 flow it took to reach 770hp from your combination. Any thought on this?? E-85 around here is scarce. It would be easier to run to the track and just get race gas.

TrickFlow heads come fully CNC ported right out of the box. I haven't had the time to do any more work with the TrickFlow heads to see if more improvements can be made to them. Looking at them I believe there is more potential. The TrickFlow 240CNC heads were not designed to be a race head but rather a better option than the typical standard port location of the Edelbrock, Stealth or Sidewinder type head. There have been other heads previously mentioned that would be a better start for a race head.
