We plumbed Shad's engine with lines going to the valve covers and we actually made all the tooling and programming for the billet valve covers, complete with the rifle bore to plumb oil to squirters aimed at the valves.
We held off on the project because they would be pricy, not to mention the aluminum will draw up some extra heat compared to stock valve covers. Our new heads will have an oiling provision to improve cooling and oiling of the valves, springs, guides, etc.
If there really is enough interest, I guess we could make a few sets for those interested, considering we have a huge stock of extruded aluminum billets to make the valve covers out of.
