Unless there are scratches on the cyl walls, I'm having trouble with the bores being "all over the place" on a fresh engine, really? Wtf? I agree with Rat, no reason for excess brg clearances. Unless You are boosted & generating a ton of bearing load at low rpm, or extended hi rpm/load that requires extra oil flow to cool them, You're just going to throw extra oil everwhere...glad You've ID'd the culprit, & taught a valuable lesson to many, if it looks, feels, or sounds wrong.....it probably is.
