Rocker oiling or lack of .

If pushing oil up the Push Rods then it seems the factory oil holes up from the #4 cam bearing should be limited and rocker shafts orientation is Nill! Yes?

Only if he's using shafts that don't get oil. If so, how are the rockers oiled where they ride on the shafts? The spring pressure pushes up on the rockers. That means they wear the bottom of the shafts first and the bottoms of the rockers where they ride on the shafts. How in the world can shaft and oiling hole orientation be "nill"?

Paint me a picture.
