    wisecos are forged and will swell more.the first time you run it get it to operating temp .take it home and let it cool temper piston .then cont break in later i think they will keep swelling the first time used can cause seizer like to here any body else who thinks this are not may start a post good luck.turn piston up side down in hole and measure piston skurt clearance that is the widest part of piston where seizer will start
