Sounds good, time to acquire a torch and some gas. My initial research says to get a MAPP torch.

Double nut can work most times. Best way is to use a Snap on stud tool with appropriate collet. I little heat doesn't hurt either.

This tool does a great job of removing studs without damage. You can get different size collets for all the different studs.

You lucked out that the stud stripped and not the case, good for you!

A cheap propane torch is fine. Heat the stud until a spritz of water sizzles. Since that stud is toast, I would use some vise grips to remove it.

I got the original stud out with double nut, still need to work on its inner neighbor that was damaged but not initially stripped.

I have a MAPP torch now, and can try with locking pliers tonight. Or stop and pick up a more specialized extractor.
There isn't enough good thread exposed on the second to enable double-nut because of the alignment sleeve.

I'm cleaning my rocker arms and barrels. One of the heads has some moderate pitting. Unsure if I need to replace it, or if it will be OK. My camshafts themselves have been redone by a shop.

^^^ I've replaced better.

I’m not sure, but would think that best practice would be to have the rocker arms re-bushed and faces restored?

I sent mine to Craig when I did my top end.

Hmm, I didn't realize you could get the faces restored. Which Craig is that?

EDIT: Figured it out: it is cgarr at g2 performance.

Related question: If I borrow cam timing tools and time, will that end up thrown off if I pull the cams later to be re-finished? I think not, based on what is actually being set.

Just a note, everything being in spec on the build, if the cams aren’t timed correctly, the motor will not run.
The shim on the stud will pull out with pliers if you twist and pull.
