IMHO, this may be a job for a pro. I recall when I had a couple of broken
manifold studs & I called a machine shop for their price to remove them. He
quoted 2 prices... one if I brought it in 'as is' and another if I brought it
in after I had "messed with it".
The second price was several times the first with no guarantee it would not be
more.
I took it in... 20 bucks & a couple of hours later I had it back with studs
removed.
