Update:
Listen to most of y’all and stuck with the stock pistons/rings. Went with a cnc ported and polished valve job and new cams. Hopefully soon (6months) I’ll be able to go with a big bore. The machine shop was great. Showed me the issues where things went wrong why and how. Looks to be too hot an ecu flash was burning things up on two cylinders. So hopefully all hood and I’ll be able to put it all back together now that i been a few weeks. Lol seriously.
