compression ratio on LQ4 with stock ls1 heads?
I'm trying to put a motor together on a budget, I thought it was a LQ9 but when I got the heads off its a LQ4, I have a Thunder racing Trak cam package, Can u run the stock heads on the 6.0 and get the compression up? and use the cam I have without flycutting? What head gaskets? And what should the compression be? Thanks, sorry or the ignorance.

Just bolting on the heads with a stock gasket will bring the compression up to almost 10:1. If you mill the heads 0.030 and use an 0.040 thick gasket you get 10.8:1. Without milling and the 0.040 gasket you get 10.3:1. Milling the heads 0.030 and running the stock gasket will net you 10.4:1. I would at least get the 0.040 gasket and it should be ok w/o flycutting.
