The "everybody makes mistakes" comment does not hold water with this situation. An engine of that caliber, being built by a shop like MM, that goes out the door without the bearing clearances being checked is absolutely inexcuseable. That's engine building 101.

If I got my motor back like the OP described, MM wouldn't even get an opportunity to fix it. If they didn't do it right the first time and made such elementary mistakes, not to mention screwed me on my old parts, they'd never get another dime of my money. I'd be expecting money and my old parts back.
