<VV> Upper Head Stud - Help!

[Frank DuVal]

I read that also, but cannot see a way to remove the studs from the 
block that would be any way more possible than just unscrewing the nuts. 
It is possible for the nut to smash the aluminum into the gap between 
the stud and head kind of locking it in place, but there are some tricks 
to that problem as well.

But I wasn't there to see what was going on. So I don't know what 
disaster they saw.

I have had, being here in the east also, many nuts not unscrew and bring 
the studs out with them. Even a few rocker studs! That's when I started 
using Vise Grips and the hot wrench to help remove just the nut.

My intent was to caution people about removing studs without a really 
good reason.
