Which heads for a 454 lsx drag race setup?

I've been thinking it would be cheaper to build a monster stoker than go the turbo route. So that being said I want to build a 454, run a single plane intake with a 4bbl throttle body, and a solid roller cam. This is all going in a heavy GTO with a TH400 4000-5000 stall. I want to be able to rev it to 7k also.

What heads should I choose?

Just buy my engine and save your self a ton of time and money. Nothing is better then a turbo setup.

At a minimum you should run an ls7 style head either Performance inductions or all pro,the best would be a c5r head

Good point. TIME being the greater savings of the two. It would take near a year to replicate your setup.

But if you can't wait, ported LS7's are good for N/A, if you're gonna spray it use the thicker deck heads by ET or All-Pro.
