.040" gasket on stock LS2?
For anyone who has installed a .040" gasket on a stock LS2 are you measuring the deck height? Most say the stock piston comes out of the block .006 but I have read this could vary up to .008-.010 which would make your quench very tight .030-.032
If that is the case factoring in piston rock would that not risk making contact?

It seems even on the high side say .010 your quench would be within the targeted 30-40 range. Either way nothing wrong with your choice it just seems everyone goes with the .040 gasket. And that leaves me to believe most are not measuring with no ill effects. The bump in compression and tighter "squish" will help make more power and ward off detonation.
