Before putting it back together I would run a home made mandrel with red scotchbrite on it to rough up the cylinder to seat the new rings. After the red SB be sure to CLEAN the jug VERY well with either dish soap and water or something like brake cleaner. You don't want any left over grit to get sucked into the engine or bearings and abrasives WILL leave grit behind.
Mastermind has a video on this site on removing aluminum transfer without acid which shows the process.
