1964 Chrysler 300K intake manifold valley pan

I have removed the intake manifold to be restored and have purchased a new intake manifold gasket (called a “valley pan”) it came with the valley pan and 2 fiber gaskets. The original gasket was only the metal valley pan with no fiber gaskets used. When I go to install the manifold do I include the fiber gaskets? Gasket set is a Felpro # 1215

Intake manifold gaskets and valley pan

I would think the extra gaskets are there in case you had to mill the head or intake. If it is all original you may want to just use the valley pan and some good sealant. Coat the cylinder block seal surfaces with oil resistant sealer. Install new seals and gasket.
