So for argument sake, where would one find a refurbished 606 cylinder head? I have dealt with Potomac German Auto in the past. That would be my first thought. Any others?

Nah, not necessarily. if the repair is done carefully you should not hydrolock the engine. If the remains of the plug is removed, I don't see why you couldn't install a custom made plug (and/or just a set screw and not worry about the compression change) in two places and seal the coolant in. if you were really worried about it, or if there is a breach in both the oil gallery and the coolant gallery, then just have someone weld it closed?

You'd have to have a lot of coolant dripping past the treads to hydrolock it...

You may consider asking this same question with some background on what we all have suggested at the practicalmachinist.com forums and/or some welding forums. Get the opinion of guys that see FUBAR parts all day and make them un-FUBAR for high $$. then post the link for us all to lurk and watch
