I'd like to replace my exhaust with some nice stainless GoWesty pipes. I'm
concerned I'll encounter problems with the head studs though, they look
really rusty and the headers haven't been removed since they were
installed 13 years and 85K miles ago. Should I be concerned and have the
job done by a pro or should I have confidence that the nuts (they're copper
I think) will come off without damaging the studs? Just don't want to end
up with my exhaust off and need to get the van to a shop to fix a stud (or
head).
