Replacing the head gasket on a 1991 Chevy Cavalier do you need to use sealant on the gasket of the intake manifold and the exhaust manifold?

No, You don't put anything on Head, Exahust or intake gaskets. CJ

actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets.

In most cases a new gasket is required, but no sealant.

You need the sealant on the ends where the supplied gaskets don't cover fully.

Not that I've heard of. Replacing the gaskets and inspecting the manifold for warping or cracks is the best way to stop intake vacuum leaks.

There should be a stud (not a bolt) threaded in to the head and the stud should have a thread sealant applied to the threads.

Yes, wherever there is a joint between 2 pipes, use exhaust sealant to prevent a bad seal between the pipes, which will prevent it blowing.
