318 piston ring gap

And.. Harbor Freight has feeler gauge sets that go down to .002" for very little $$. Check all you piston side clearances.... the wear can and does vary.

Sounds pretty solid so far. Make sure they don't over do it with the fresh hone and open things up a lot. Interesting machining on the tops and side of the lifter bores. I've never seen one of those block.
