Reason being, I had a problem with my main girdle and the holes not being drilled true. I had to bore them out.

Johnny, I really wouldn't worry about it at all. If all your bearing clearances were fine, let it go.

What did the piston manufacturer recommend as a piston-to-bore clearance? I guess it differs from each piston manufacturer, but I think mine was .004". Like I said before, you're dealing with high compression...it's not gonna turn like it does with just the crank in the block. You're turning a lot of mass...with a lot of compression.
