A few thoughts,

1) One cannot see the rod bearings without disassembly and those are stressed parts.

2) The main bearing saddles do not remain in alignment after the case is split on magnesium-cased engines,..especially the '76-'77 cars due to excess heat. I would have the case align-honed to see if that will clean it up.

3) I would not use Time-serts,..Case Savers are a much better repair for reinforcing the threads on these mag cases. This is done in a milling machine and cannot be accurately done by hand.
