I don't understand how we got into the subject of forged pistions and the clearances needed for such when it seems you have a good stock usable Bore with stock cast factory pistions.
What am I missing here?
Ball hone it , wash it out 3 times over, clean out any crap in the ring grooves with the tool you can buy for that then re-ring it and have good summer fun with it.
Also please note that when your running a cylinder Bore that likely has a taper to it and will be a tad oversized after the honin, then you do not want to run a plain iron compression ring, you want a ductile iron ring.
The flexing that the rings experience by the out of spec Bore will quickly fatigued a plain iron ring and reduce its outward tension needed to seal.
A ductile iron ring will hold up far longer in a used Bore .
