Can't find find anything specific in the '57 shop manual re sealant for a Fel Pro, rubber style Valley cover gasket.. I have on hand Permatex Ultra Copper & #1 Form a Gasket, both in tubes. & brush on High Tack. The latter I'd prefer not to use as it's messy to work with. Also, can someone refresh my forgetful mind as to whether or not the intake manifold gaskets need  any type of spray or sealent?  Thanks
