Default Compression Ratio help

Hey guys, I have a question about the compression ratio of this car I just bought. It's a 02 ls1 with a 99 model LS1 block. The guy says the heads are 241 casting cyl heads, cut .030. Would someone estimate the ratio for me. My plans are to put a 150 shot and I'm just wondering if I can leave the heads or if I have to swap to a 6.0l head.
