Fel-Pro PermaTorque MLS head gaskets provide the robust seal needed to contain peak combustion pressures and temperatures—and to withstand the significant casting motion encountered in many of today's automotive engines. The gaskets feature multiple layers of steel, precisely engineered sealing beads, and advanced polymer coatings to maintain a proper contact pressure between the cylinder head and block. Unlike other multi-layer steel head gaskets, PermaTorque MLS seals also include a proprietary blue aftermarket coating that accommodates a wider range of surface finishes. These gaskets are manufactured using precision tooling to ensure exact sealing bead location and profile. Order the model recommended for your specific vehicle and engine application.
