How does oil get from an ARDUN head back into the engine?

On the downhill side of each head, oil leaves through a port and a hose to a fitting on the oil pan. The rest drains down the holes where the push rods come up, where the valves and guides used to be. On the intake side that is no problem: it is a straight shot down to the valve valley and back to the pan.
