We mostly went with Engine Quest because they're widely used in circle track as a legal stock type classes iron head that flows better than a Vortec, and the price is way better than most aftermarket heads. Many racers have good luck with them. Not sure how ours got so whacked out, if it was from the factory or the engine builder that sold them to us but either way it looks like they'll work out. With the retro roller cam we have it should be a solid 425-450 hp and about 480 ft lbs, pretty typical for this complete set up. Agreed with the LS swap, Roman has a 6.0L LS for his Cutlass wagon's future rebuild.
