For anyone contemplating exhaust manifold gasket replacement: As part of a dual exhaust conversion (nearly finished), I replaced the carbon steel nuts on my exhaust manifold studs with stainless. Original studs were left in place -- only the nuts (and little 1/8" thick stainless washers) were changed. Of course the original nuts were badly rusted and stuck to the studs. Rather than attempt to turn them, quite possibly snapping the studs, I used a nut splitter and cold chisel to pop them off. Worked excellently. Chased the stud threads and slipped on replacement nuts as easily as new. I do not own an acetylene torch. MAPP gas in my plumber's torch might have worked, but this was far easier.
