    Note:To insure proper manifold to cylinder head sealing, Edelbrock recommends using an embossed intake gasket like Fel-Pro's Printoseal or Mr.Gasket's Ultra Seal. Fel-Pro's Perma Torque Blue and other similar gaskets do not compress well when used with an aluminum intake manifold and may cause vacuum leaks.
