You might want to use a different set of heads, here are a couple of suggestions:

I would also move the LSA of the cam closer to optimum, which will be around 108*. For your vaccum brakes a 110 LSA will probably be as far as you would want to venture. Then depending on which set of heads you use, find the best advancement for the ICL.

Brett Foote Well with a regular Fel-pro 1003 head gasket you compression ratio will be approx. 9.77:1. You should be around 446 HP & 473 TQ if everything is ideal according to my Dynomation program. For the money I would deck the block as there are several benefits to doing so. If you get your compression up over 10:1 then I would say that the cam you have would be ok, but if you don't then I would buy a custom grind cam to pull your components together.

When I has my mild LT1 Z I was told to get a 3200 stall. Factory cam and all.
Everyone remember he has the 8.5 10 bolt, not the junk 7.5
