Jake recommended I do this for my engine. Apparently this involves welding on a 1/2" fitting to the cover. Anyone got pics?

As Herb noted, they leak unless you have an external multi-stage dry sump pump system as the valve covers will fill with oil at high RPMs and out it will come. To prevent this you need a vacuum in the crankcase to help the oil flow down the push rod tubes.
