Getting a complete seal seems to be a lot of trouble for little protection, particularly when the intake cups are actually perforated to allow air in, so that the oil can be sucked out. Messy knuckles are usually a result of over-oiling: more being pumped in than can be sucked back out. For '41 and later heads that do not have 'adjustable' rocker shafts, I commonly drill a .060" hole in a rivet that can be slipped into the bottom fitting of the overhead oil line as a metering orifice. This has proved adequate to lube,yet cleans up motors even when equipped with modern high-volume pumps...Cotten
