<VV> Upper Head Stud - Help!

[Frank DuVal]

Jay,

This is a hard lesson, but never remove the top studs unless they just 
unscrew easily. This would be because of other problems like previous 
overheating.

Use Vise Grips to hold the studs from unscrewing while removing the head 
nuts. I have used the nuts with the locking ridges, and they will come 
off, but do shave some of the aluminum. You can always use a washer the 
second time if a lot of aluminum is missing, but I haven't seen it.

Sounds like you have a plan now.  Good luck! It will go back together.
