intake gasket

I orderd a intake gasket for the 55 from rock auto. they sent me a metal gasket by felpro. is this the gasket I want to use? never seen a metal gasket for intake before. if so what kind of sealer should I use?

The Oldsmobile shop manual recommends to dip the threads of the manifold bolts in C.P.#9 sealer and torque to 22-26 ft.-lbs. according to the designated sequence shown in the manual.
