How to open up rocker arm oil passages.

On SBM the rocker shafts are directional. Not sure about slants... Are you sure you got the shaft in in the correct orientation?

Yep, I'm certain. Lots of oil coming out between the rocker arms and spacers, and some rockers have oil flowing along the top groove. There is also a flat spot on the end of the shaft to help with orientation.
