Yes & No ! It's a trick question. If there are studs in the head and
they do not come out when you remove the nuts then you have two choices. Try
to remove the studs or remove the header pipe which will entail breaking the
connection at the collector. Actually, you should remove the header pipe
anyways to clean up the surface of the exhaust port gasket surface. If it
has been leaking for a while the surface will be not acceptable to a new
gasket therefore it won't last long. The other thing that's going to happen
is more than likely one or more of the studs will break off and you will be
obliged to drill the remainder out and tap new threads. I highly recommend
you install helicoils or time-serts at this point so you will have nice new
good strong threads to hold new stainless steel bolts or studs, your choice,
just make sure the bolts you use will not be too long but long enough to get
a good hold on the threads in the head. All of this is easy to do at the
front of the motor, relatively speaking of course. BUT, at the rear of the
motor you run into a bit of a problem due to the crap in the way. If you
need to renew the threads at this end you will need to drop the motor enough
to get clearance for the drill to operate. Good luck ! All this is why I do
not give quotes on installing a new exhaust system on a Vanagon engine.
Could be easy could be a major PITA. Last one I did all four of the exhaust
studs at the front broke off and I had to drill, tap and helicoil four new
holes. The rear had only one, lower LH side one screw up, and I was able to
run a tap in and out and clean up the threads well enough to get a new stud
in. Whew ! That was luck that time around,
