Well, this is a 440 and the book calls for .004" ring to land clearance. I'm getting right between .004" and .005" on all pistons. A few original rings were stuck/frozen in the grooves, and I had to use a very fine emery (400) to get the grooves clean, which apparently opened a few groove areas to .005" and is my main concern. Piston to bore clearance seems fine. There are some minor scratches (small stuff) on the skirts, and a little vertical roughness on some sides between the tops and the upper ring lands (which appear to be scratches as I see no evidence of burning). I have already smoothed a lot of this out with 600 paper, but can't afford any coating.

I Think they will be okay but wanted to check. I can post a pic if that will help.
