360 hydraulic lifter valve lash

I know, that's what I was getting at. Did you notice anything odd when you pulled it apart.

it ran good, i was able to hear it run and i actually pulled it out myself. internally it was really clean . i didnt think about checking the valve train, but it didnt clack and rattle like it does now. im at a loss here, i was hoping the lifters were to blame lol
