    What are the last 3 casting numbers and what do you want to do with them or your application?

    those are pretty good heads you have there will support up to 600+hp with a little work....contact Curtis Boggs at Raceflow Development he should be able to make them better.....

    Not sure, but does Curtis work on cast iron heads? I just bought the 24 degree Edelbrock heads from him and I will be dynoing in 3 weeks...cant wait.

    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.
