    I was being stupid and was in a rush to get my motor going for college. The ring was somewhat tough to move in the piston groove. My fault, live and learn. Ill soon find out but i think the heads are fine.:drive:

    if the ring is not in the groove all the way and you force it in you will break the ring and piston
    side groove between that ring and the next ring then it make the piston fail ,

    Heart surgeons dont rush a triple bypass.

    I doubt it.

    things id check

    distributor gear (old dist on roller cam will eat the gear and cause it to get out of time)

    id take the head back to the machine shop and have them double check there work and make sure the valves are sealing

    pull the lifters and make sure there is no rollers broken make sure all the valves are opening and closing

    and correct your valve train geometry problems
