Please help!!!!! LQ4???

I have a LQ4 engine with the stock rods and pistons. I know that the compression is around 9.5 with factory 71cc heads. My question is I have a set of 5.3 heads ported out with 2.02...1.60 valves. What would my compression be on the LQ4 factory pistons and a 61cc head???? please help. I wanted to run these heads since I have them and I have no money...haha **** why cant we all be rich? Thanks for any help
