My heads are at 60cc now. I am running the thin copper FelPro head gasket.
Any idea on my compression ratio?
This is on a stock 1988 L98 short block.

Please define "thin" What is the compressed thickness of the copper head "templates"? I hesitate to use the term "gasket", since it probably won't be one of those for very long.
With exact head gasket compressed thickness, deck height, piston dome/dish volume, bore, gasket bore, and chamber volume, I can give you a nearly exact static compression ratio.
Or, you can find it for yourself:
Engine Calculations.xls If you can use an Excel spreadsheet, it's fairly close.

I'll take a WAG. How about 9.4:1.
