Low oil on valves Chevy 350?

my question i primed my 1984 chev new 350 5.7 from the distribuator only got oil on all the valves on the passanger side none on the passanger side why

I don't think you have anything to worry about. It's probably just a case of not spinning the pump fast enough to push oil down both sides of the oil galley. If you have pressure on the gauge when spinning the pump, go ahead and finish up the installation.
