Thanks Dave,
I like the idea of a 90 degree drill!
I have a dremel and can attach a 90 degree device
to it, and I hope that I can reach the last stud.
Since the studs are heated up and cooled down so
often, will that make the studs softer or harder?
Are there special drills available for this kind of
job then?
I don't know for sure if my skills are good enough
(the only way to find out is trying I am afraid..) but at least I think that I
have the patience.
Have a nice day too,
Rob

Subject: Re: IML: Problem with exhaust
manifold studs...
Rob, all I can say is the out-look is grim.Drilling the studs out will
take patients, and skill, with the drill.
The only way to access the back stud, would be a 90degree drill,
with a helper with a good eye to keep you in proper alignment. If you choose
to use the remaining studs to hold the manifold in place, keep in mind the
manifold uses all the studs to help transfer the heat from the
manifold to the cylinder head. Thats why there were no manifold gaskets on the
manifolds from the factory. The results may lead to a cracked manifold, or
exhaust leaks. In any event, I don't see an easy fix.Ya'll have a nice day,
Dave.
