350 Small Block Oil Passage Tracing to Chevy Rockers. Kendall Camonics Cam

No oil to the rockers.. Oil Pressure is 75lbs. Oil to the cam. But not to rockers. After turning the engine 90 degrees or so at a time and then spinning the oil pump I DID get oil to the rockers. I Always do this to my engine before I start it but this time the oil just didn't pump into the rockers as I have seen it do 20 or so times prior to this event. The engine has been sitting for a few years but with the oil pressure 75lbs I expected to see oil up top right away. Total time for spinning the pump and oil in the rockers was around 5-7 minutes. I use a Camonics cam, solid lifter, 530 lift I&E, 300 duration. It was designed for Vic Eldebrock and the Victor Jr manifold. 800DP Holley. 10:1 flat top pistons. spun balanced. 1 3/4" Hooker "super competition" headers.
