If the Cleveland has the factory 4 V heads with too big on the intake and a constipated exhaust port, then I'm thinking Camshaft 1 will make more Hp because it needs the overlap, but I think it could use more duration on the exhaust. Therefore I'm not certain, as Camshaft 2 may do better. It should give much better low end torque. I only expect 20 Hp difference.

As you said, this is hard to do not knowing what the heads are.
I know less than most of you about this stuff, but this is the way I would have generally guessed, as well... emphasis on guessed! I would not be able to predict a value for the difference, though... no way.
