Shot adjusters and pushrods

The adjusters are about 2 threads out,

That's probably your issue. You need more exposed ball than that. It can't pivot in the cup if there's not enough ball exposed. JMO

I had that happen on a block, i had a machine shop do the bearings and the cam wouldn't go in.. i inspect it and the bearings don't line up with the oiling holes, the machinist told me i spun the cam bearings putting the cam in... really?

A little different scenario here, whoever was supposed to drill out the oiling holes must have gone for coffee
As to your situation, everyone knows you shouldn't install a cam upside down
