Me personally I would do a set of Tooley 245 heads rubbed over with the intake ported to match then a badass setup from nitrous outlet if I was go spray. Maybe even a direct port nitrous setup.
Plenty of cars running 9s and 10s on motor with a Fast intake and hydraulic roller with cathedral heads 205cc-245cc intake runner.
I kind of agree with that. Switching to Square port LS3/7 style heads has cost factors like complete rocker setups and a new manifold when larger cathederal 235 and up will do the job, that's kind of how I"m leaning anyway. Though TFS's site says 4.125" or bigger bore for their large cathedral heads
