Putting in the header pipes this afternoon- driver's side goes right in no issues. Discover one of the studs on passenger side is stripped. Of course I didn't realize this when rebuilding the engine.

Any ideas on how to back the stud out of the head? Not a lot of room in there to work...

TIA- search function didn't help much... Found a Lisle stud removal tool but don't think there is enough room to fit it in there. Trying to think what would fit that would grip the stud tight enough to twist it out.

When removing the nuts a few years ago in the beginning of the restoration (yes, it's taking that long) a couple studs came out with the nut- wish that would have happened here!!

If you go welding a nut to the stud then heating the base, I'd recommend then cooling it with water until you can put your lips on it. The metals heat at different rates being aluminum and steel- if it's not cooled you stand the chance of the steel pulling the aluminum threads with it. When they're cooled it also happens at different rates and it usually helps the metals break free of each other. You may even have to do it a couple of times and like Cap'n sez, work it back and forth gently to get some movement and take it easy.
