Closed chambers gone bad… that’s a wrap

Seems the two decks are at very different heights. Those numbers aren't even worst case with the piston tilted and at the high point? It is possible the rod lengths are off or crank was ground poorly for some of the variation, but decks are different. When I measured my standard bore (with some wear) '71 340, I was getting mostly 0.026" - 0.032" above deck but that was at max tilt. They are a few thousandths less in the middle of the stock pistons. I figured I would need a .065"-0.070" gasket if I put on a set of closed chamber aluminum heads. That may be a moot point now because I think I've decided to have it bored .020 over (.030 if it doesn't clean up), rather than re-ring and send it. Just a little too much bore taper for my liking after re-hone.
