It's actually been a number of years since I had the work done- the engine sat bolted to a stand with a plastic bag over it until last year. The engine shop in question is the only game in town, once upon a time they had a very good reputation but somewheres in the last 20 years or so they've lost that. I wasn't aware of their issues until after I had got the engine back. In point of fact after I got it back one person told me that he had his M38 L head rebuilt there & a rear main failed within 200 miles. They did not do a proper cleaning on the block, it wasn't hot tanked & they did not remove the gallery plugs- when I did oil came running out And this- The polishing on the crank is something I'm willing to undertake myself, there's no trace of wear at all, all I'd be doing is brightening it up a bit & removing the dark rings left by in the middles from the bearing oil passages. With the time that's passed, plus I can't find the work order anymore, plus I can't guarantee that with all the work I did on it I didn't contaminate it myself, plus their current reputation I really just want to avoid any future dealings with them, including letting them get their hands on my spare, apparently good, crank.
