Pistons protruding

[Charles P]

If the gaskets do not overlap does a mere .008 matter? Assuming use of a conventional gasket

I think the eight thou might matter if there is a lot of crank whip.

It's a 1.5" crank. 
My basic maths tells me that a 1.5" bar is about 1.7 times stiffer than a 1 5/16 so how much more will they really protrude under whipping? This probably isn't the same number as the "20 thou" frequently bandied, probably because Jack French said it in the 50's.
Turning down the piston crowns by a few thou would seem a lot easier than messing about with shims under the block.
