It would probably be safe to say that The Grump had MANY, MANY sets of these cylinder heads. In fact, it's probably a bad thing because there's no telling what's been done to them such as angle milling, etc. Be interesting to see what happens when they're mated to a stock block and stock intake manifold. Someone paid a lot of money just to be able to point at that 'JENKINS' stamp at car shows for bragging rights.
