Rocker shaft oil passage?

Thanks to all who replied, I thought sure I had posted already but must have missed it somehow, sounds like something I do. After running a bit longer we started getting oil to the top end, now to determine if the slant will survive for some road duty or if have to move right on to hemi swap. Right now sorting out wiring after 40 years hibernation. What is it with rodents and wires. In pinch I've had to strip a wire with my teeth and even new clean wire wasn't appetizing.....anyways.......off to the classified section iso back up lights '67 Merry Christmas and happy/safe holidays to all.
