2005 exhaust manifold.

[Clcutlass]

I noticed while rebuilding the supercharger that the end of the exhaust manifold is extremely corroded. I have a used one on the way and was planning the job. None of the details drawings show a gasket used. Is there a gasket used on this or a recommended sealant. Are the manifold bolts easy to come out, they look very slight.
