REPLACING EXHOURST MANIFOLD GASKET DRY OR WITH SEALENT ON TC

Personally I always install dry and haven't had any issues. I've heard of people using sealer but I haven't found it necessary.

I used Loctite 5990 copper exhaust sealant on the joint between manifold and pipe. No leaks.

I used that stuff on a troublesome Studebaker once. It worked well.
