Pushrod oiling - do I need it?

Yes, thanks, I had figured that out. Understand about blocking the passage in the deck is an option and that the proper pushrod oiling rocker arms are needed when the passage is blocked.

Like your picture, the oil hole in the Hughes rockers is in the back of the shaft bore and goes through the adjuster screw relief area, not the threads. It’s better than nothing but it’s not direct, pressurized oil.

I’ve decided against pushrod oiling but am glad I asked, I learned a few things.
