OK have not found any casting numbers on the heads, factory cast iron. intake is A factory cast iron 4 barrel quick fuel HR-750 dabble pumper, HP exhaust manifolds.
Ok, a compression test on two cylinders would be enough, however, even without that info, I would still run the cam I posted instead of the one you currently have . Other mfg's make similar cams and it would be hard to tell the difference between them by the seat of your pants . I typically use Comp, Lunati, and Howards cams.
It would still be helpful if you told us what you like and don't like about the current cam.
Do you want more lope at idle?
Do you want one that hits a little harder when it comes on the power band?
Hoe far does your current cam rev?
Can you live with a few less revs if you get better power everywhere else?
