might have to pull one piston out and look for tell tale signs
it's the oil in each pot that's throwing me off

Right I think it has to be something that the machine shop did because this wasn't happening before the valve job.
But assuming the head is in order I have heard that some cases after a valve job the increase in vacuum can pull oil past the rings. But I don't feel like that is the case because of the pattern of oil that is on the pistons and leak down results that I got.
