KB HyperT's?

I would not worry about the 1-2 point in compression. It's moot.
What con rods are in the engine now? If it is a factory rod, simply stay with a standard .039 Fel-Pro and be good with it. Unless the slugs are positive in height, you may want a little more room. No sense in pushing it with Hyper slugs. None what so ever.

You can find a little more power with a 750 carb a d different cam. Run a split duration cam in what ever style your going to run. (Hyd. Or solid or roller etc... )
