I paid no attention to the pistons I took out except to inspect for condition. I took them to the machine shop with the block. They removed the pistons to recondition the rods, and I assume that they threw them away.

I got the new pistons, put them on the rods and began assembling the engine.

Again, is the tolerance of pistons OD close enough that I can change the pistons with the same oversize, but different head recess style and find that they fit with the same clearance as the set used to hone fit the block?

Thanks for the information,
