Was your original failure (the cracked cylinder wall) and this one (#3 main/journal bearings) on the same cylinder? If they were, I would not use that cylinder head again. I'm no expert but that seems like too much of a coincidence to have a 'not too common' failure occur in a cylinder wall and then overpressurize the same cylinder again this time leading to bearing failure. The only things in common between the two failures are crankshaft, connecting rods and cylinder head. I wouldn't have any of those things back in my engine. Seems like both events could have been caused by overpressurization of that cylinder.
