There are two schools on using the factory-type valley pan or omitting it for Edelbrock’s PN 7213 intake manifold gaskets. The Edelbrock gaskets will conform to cylinder head surface irregularities better, but the stock-type valley pan gasket will keep hot oil off the bottom of the intake and further reduce the possibility of the PCV valve sucking oil. We bought a new valley gasket and coated both sides with Permatex Aviation Form-A-Gasket and ran a thick bead of Permatex Right Stuff gasket maker across the valley ends and around the water passages.
