Kumar,
Be careful with manipulating gasket thickness. You want to maintain good quench/squish.
Often slightly higher comp with better quench is less prone to detonation that lower comp with poor quench.

I would defentially not run that big of a gasket.
You can get down to 9.5:1 with no problem on a stock LS1 with a 74cc head.
9:1 will be tough. Anyways 9.5:1 will be fine.
Look at all the stock Z06's with 10.5:1 running FI.
