Assessing cylinder sleeves (a little long)

Hey, y'all.

I have a Ferguson TO-30 torn down in my shop right now and need some advice on assessing sleeves. I bought this tractor from a fellow who thought it had broken rings. Anyway, when I pulled the engine apart I found that the rings on three cylinders (the three that were burning oil badly) had about 0.125" end gap and about 0.1" clearance in the ring gap. Clearly not even close to correct. It looks to me like someone re-ringed it without using the correct rings-- the rings aren't worn or broken, just the wrong size! Well, the pistons look fine and the cylinder sleeves look pretty good to me. According to my measurements, they are brand new overbore sleeves and pistons. One has a chip out of the bottom of the sleeve, but it is well below where the sleeve exits the block above the crank. Would y'all reuse these sleeves, and what else would you look at besides micrometer bore measurements to decide whether you'd replace them?

Thanks a million,
Darren
