pistons dont last forever,they are brittle and over time get tiny stress cracks and weak spots especially around the skirts and the intake window edges, they will eventually fail and cause unneeded $$$$$$ trouble down the road ,take the jugs to a reputable shop (good luck) and have them check them out and see if yo uneed ot go.060 over or can get away with honing ,price is usually 45$ a hole to bore oversizes and new wiseco piston kits that include everything and gaskets are like 150$,its cheapo insurance bro
