Help with Head Gasket selection

Yessir. While you can chase your tail on this stuff, .010" difference is almost 0.2 points in compression so it is worth some work to reduce the variation IMHO. My son and I worked his engine down to .002" variation, max/min.

BTW, are the heights you listed in order of the cylinder numbers, or in order of the 4 odd cylinder numbers first, and then the 4 even cylinder numbers? If the latter, then there is a pattern on the deck work.
