How do ARDUN heads get oil, and how does it drain back?

A Flathead sends no oil to its heads: the cam and lifters are splash lubricated, and only the cam bearings are pressure fed. An ARDUN head has a fitting at the back that supplies oil from the engine, one line to each head. Some of that oil returns down the push rod tubes, but most runs by gravity to a drain on the head, and tubing carries it from there to a fitting on the oil pan.
