    So what do you plan to do about the .010" taper? If you fit the rings to the big end they will be too tight at the other end. I suppose with a lot of work and patience you could straighten it up a bit.

    I guess it is your call. Personally I’d hone it real lightly and slap some new standard rings in it, and replace that scored piston and run it.
