<VV> Upper Head Stud - Help!

[airvair at earthlink.net]

Frank,

It wasn't that the mechanic "accidentally" unscrewed them. He intentionall did it, because the heads were damaged in such a way that thet were locked around the studs. Thus removing the studs was the only way the head could be removed. He told me personally.

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.
