I'm extremely familiar with it since I've done it before working in a machine shop. Unless an engine spun a main and damaged the block, there is zero need to change the crankshaft position. Lemmie splain. The main caps are remover and slightly milled where they meet the block. Now, we have an egg shaped crankshaft main bore, but it's all on the cap side.
The block is the set up in the align hone or bore and JUST SKIMMED in the block side to barely even knock the dust off, while the main caps are trued. It does not change the crank position one iota. This is the correct way and if the shop didn't do that, what else are they doing or not doing?
That was my point. Of course, doing it "their way" certainly works, but then you're faced with an oddball timing chain.
