What would you do,???.

I was looking up your inquire and in the heavy machinery/farm tractor forums, their recommendation is to hone and run. I 'think" they say to use cast iron rings, not chrome rings. Maybe a moly coated ring would fill in some imperfections? Had a 340 that one cylinder had .008" piston to wall clearance and ran fine. Guess you could hone it a bunch to try and remove the pits. Good luck!
