Old lifters with new cam? I would not have done that. Even with less than an hour that was a big risk. I'd also put new lifters this time.

There is going to be metal in the bottom end now. Since you are not deep into the short block, you might consider finding a later TBI or Vortec 350 that already has a roller cam and put your heads on it. Just a thought.
