If I have a stock internal ls1 @ 10.9-1 comp. ratio with stage 2 ZO6 heads. and I put a 383 stroker kit with forged -26cc pistons , what would that put my comp. at?

I know stroker kits increase compression . so how much would the dished piston decrease it?

would there be any negative side effects of going with a deep dished piston vs. a -7 or -14cc forged piston?

this is for a FI car that I'm looking at throwing 12-15psi, so what would be the best thing without changing the heads!
