With motor work that extensive, it could be a lot of things ... maybe the way the valvetrain went back together?

If they took apart the head to mill it, did the shop use all new valve seals when they put everything back together?

Document it and see if it doesn't settle down after a few thousand miles.

if the head gasket was just replaced and nothing else was replaced. id retorque the head bolts. im using your bottom end in my dime and i retorqued my head bolts at 50 ft lbs. you might want to double check for the naps-z head bolts. keep us updated.

Simplest idea is that it probably got some junk in the rings while the head was off.
