Update.
Got Jethro's head back from the new to me machine shop. I horse traded him a razor sharp Case folding knife, and a 3 speed transmission for the 848. He threw in a spitload of sweet corn and a head of cabbage. We surely both walked away thinking that we made out like bandits.
The machine dhop did the following:
All new intake valves, and new stainless steel exhaust valves.
New valve guides, and new valve seats. (the old seats were hammered too deep to retain the proper geometry of the rocker arms.
They shaved just the bare minimum from the head to make it true.
They milled the side of the head where the manifold goes.
He charged me $400.00 for rebuilding a head which literally needed everything. That is less than half of what my now former machine shop wanted to charge me.
I just got done priming it, and am fixin to paint it dark gray.
Tomorrow it is going back on the engine.
