Thanks Bill, I'm now thinking that I can set up an acid wash loop with my stainless head brewing pump once it is re-assembled and then do a thorough flush. I was worried about the relative difference in hardness of the valve seat patch, weld bead is supposed to be tougher than the steel it welds right? Either way, the pitting is telling me that it's time to keep an eye out for a new head anyway and hopefully I can keep this one chugging away until I happen upon one in a yard sale or marine junk yard one day.

I have been using degreaser and a medium abrasive sponge to remove the corrosion, rust and residue from the head, gasket and block mating surfaces and then polishing with 800-1200 wet sanding paper. I should have the engine back together today with a little luck. (knocking on wood)
