Matched to Edelbrock Performer, Performer RPM and Victor Jr. cylinder heads and manifolds, our intake gaskets deliver optimal flow and performance. The new MP-2N Micropore® technology uses no solvents, so that our gaskets are environmentally friendly. Impenetrable to the majority of chemicals, this composite of synthetic fiber delivers high recovery under load. When compressed, the gasket will adapt to imperfections of the surface to be sealed, even when lower flange pressures are applied. A nitrile bead around each port improves the seal even more. Edelbrock intake gaskets are an Edelbrock product.
