Hughes heads?

GREAT INFO! I really appreciate it. I'm really trying to get the motor in the low 700's I know the best head is probably the Indy 440-1 but just don't feel like spending the $4,500 or whatever it is... given all the info here I think ill end up with the trick flow 270's

Trick Flow 270 heads will easily make 700 hp. Here is a video from the dyno session when I ran my pump gas 470 with the 270 heads. We made right at 750 hp and that was with a standard port intake. With a good max wedge intake this engine will probably make 770 or 780 hp. This engine is being run on premium pump gas so drive to the gas station fill up and drive it to the track and run 9's.
