What head gasket are you planning to run? Is it a GM head or aftermarket (so we know roughly how many cc's were taken with the milling)? And I am assuming you mean it is a stock LS1 bottom end by your avatar, correct??

3.898" bore, stock stroke, assuming pistons out of the hole .007", and calling the GM gasket .055" and the chambers 63cc (might be a few tenths less, but this is close enough for this purpose) you'll be at about 10.8:1 static.
