Rick, those heads have some good potential. My 469 (0.070 over 454) had those heads on it with mild port job (2.25 intakes and 1.88 exhaust) 13.9 compression, CompCam, Victor Jr. intake, and 1000 cfm carb, and it dynoed at 693 hp @ 7300 rpm. In one of our classes they have to run OEM cast iron heads and that casting # and the 990's are the ones they use. I know of a couple other motors that middle 700 hp levels and one that is over 800 on the dyno. It all depends on how much $$$ you want to spend.
