Dan,

         I didn't have a problem with those bolts, but had a similar
problem where the lower pipe attached to my driver's side head. I ended up
cutting off the pipe so I had enough room to get a vice grip on the bolt
and spin it (the pipes were bad enough that I was replacing 'em all anyway).

         Dunno if that will work for you, since you have the bad luck to be
working in an even less accessible area... I had to cut about a
quarter-inch off my allen wrench just to get in there.

         If you can point a big screwdriver at it, maybe cutting a slot in
the head with a dremel will let you get some leverage?

Good luck!

Tim
