Stop in for a cup of coffee

Wanting to ensure I do this right.

I have about 90 psi on the oil pressure gauge.
Been running the drill/ priming rod for just over an hour and half with 1/4 turn on the crank every 15 minutes.

Oil filter is warm

Still no oil at the lifters... am I just being impatient?
The rocker shafts could be bolted on wrong. Pull the shafts and then spin it. You may get oiled.
