Every time I've ever looked at it, it's six one way, half a dozen the other.

This is where our disagreement is though. I DONT think you have to do all the same things to the newer shortblocks. You can, and its better to do so, I wouldn't argue that. But also, I think there is enough evidence of dudes running factory short blocks now that it wouldn't bother me that much to do the same thing.
I would feel at least marginally confident just re-ringing a used LS block. Maybe bearings. But otherwise all OEM parts. I wouldn't feel the same about a junkyard 400. You are always gambling with used parts, but I think the gamble is way less with a newer motor.
