Well Im sure there are a few that has Desk-top Dyno or some other programs but Im sure they will need more specific specs than you have provided....(ie: Crane Cam (slightly larger than stock) ) Just an observation.....

Go onto comp cams website and download their camquest program. Pretty cool and fun to play what if? Good luck.

is the compression 10.5 with the heads, or is it 9.5 after you factor in thermal efficiency?

with aluminum heads, you lose about 1 compression (not literally) because the aluminum doesnt hold in the heat
so, your engine will put out power like it has 8.5 to 1
