Oldsmobile oil system mods

Hey Alan I was priming an olds 455 with oil I had built and it was impossible to prime with the valve covers off. I proceded to section an old valve cover to see how much oil was under valve cover and was amazed. I installed some smith bros pushrods with a .030 oil hole and did my priming again and still think there is too much oil up top. Any other ideas other than what you posted. Did the mods already!
