Round is better
Looks like the crank worked fine out-of-round,
It comes down to whatever you can live with, as it seems the engine was able to live with it.

As for machining the deck surface, with 187K, the surface is not likely to 'clean' with a .0015" cut, considering aluminum and 'floating' cylinders. The idea is to cut the same from each deck, unless going to the trouble to measure each corner and 'blueprint' the deck.

LAN has done a few, he would have a better perspective than I would. However, .006 sounds very reasonable for clean, flat and true

Did LAN supply the pistons? If so, ask him about the deck surface, he should be happy to comment about the .006" cut.
