new 360 oil pressure problems

Got all done rebuilding my 360 nd i went to prime the oil pump nd i got no pressure...i saw that i forgot a lifter galley plug thru the dist hole nd put that in thinking that would solve my problem caus i was getting lots of oil thru it so o tried it again nd nothin...do i have a lifter issue?...I've got w2 heads oiling thru the block tp the head wit solid push rods nd a roller cam its a racer brown cam...its a older magnum block wit the oil hole for the head nd the obviously la shaft rockers its not oiling thru the pushrods but its got the head style oiling holes the oils getting to the lifter galley caus it came out of that plug. Am i missing something?
