How do the rocker arms get oil on an ARDUN head?

A stock Flathead has no oil in the top of the engine, so the designers had to add it. On Steve's updated heads, oil comes from the engine into a casting on the head, travels through external fittings, and feeds passages inside the hollow rocker shafts. Each rocker arm has an oil hole and is drilled so oil reaches the roller on top of each valve, intake and exhaust.
