340 Oil Priming Question First Start

Guy’s need your help. Again I am new to C-SBM oiling.
My wife and I worked on priming the oil manually. We held a constant 60psi while I slowly rotated the motor.
I never saw much more than drips out of the bottoms of the rockers.
I expected at one point to see it come through the small holes (see pic) on the rocker arms but those remained dry on both sides.
I rotated the crank 4 times through the complete valve sequence.

What are your thoughts?
