Hey, I am quoting myself. Here is a question I didn't ask. How do you get old pitted studs out of a head? Drill and tap? How successful is that? I would think that alone is best left to a machine shop. I mean, I am well intentioned but they may be able to have them out in minutes, while I am breaking bits off in the stud. I mean, take it to a chop to have them pull them out if there is a hint of trouble. Ask me how I know that one.

As a final point, I want to share something Colin pointed out to me about these studs. The ones that face the front of the vehicle pit and corrode faster than the back ones, simply because the front ones get road splash in addition to heat and corrosion. Keep that in mind for reference.
Up, up the long, delirious, burning blue, I’ve topped the wind-swept heights with easy grace. Where never lark, or even eagle flew. And, while with silent, lifting mind I've trod, The high untrespassed sanctity of space, Put out my hand, and touched the face of God.

John Muir goes through the options in How To Keep Your VW Alive, to that I add "patience and a prayer". You start simple and work your way towards difficult. PB Blaster + hammer is a good start, not big hits, just tapping to break up the bonds between rust and aluminum. While you are tapping with the hammer, you are also making a nice flat shiny surface for guessing the exact center of the stud when you move on to the next step of center punching so you can drill with the smallest possible bit right down the center of the stud, then shine up every single other bit in the box as you drill successively larger holes right down the center of the stud. Some people switch to E-Z-Outs at this point, I don't. I go straight to hitting nirvana where the threads of the stud can be "un-wound" out of the aluminum with your fingers. Happens once a century or so.

Honestly, I don't know if I trust anyone else working on my Bus.
Sure, working on it with friends is cool, but the thought of dropping it off at a garage makes me crazy. You can't see what they are doing...and do they really understand the differences between it and a Ford minivan?

A VW shop does, but they are production driven. No way are they going to gently restore each and every bolt.

Right on. And we don't even have one of those here anymore.
