Memory isn't what it used to be, but I seem to remember that the safe range was up to .049". Way I remember it was the standard gasket thickness of .039" allowed up to .010" in the hole before the possibility of detonation really increased.

The other way around the problem is to open up the quench area large enough that it also won't cause detonation problems. I can't remember whether it was pretty low around .080" or higher in the range of .120"? The tighter quench is definitely the way to go, but sometimes you don't get to have what you want. Basically, the big number was why we got away with milling out the old TRW forged pistons (years ago before the beautiful D-shaped dished pistons became available) to lower compression without going into ping city.
