Fel-Pro PermaTorque head gaskets are meticulously crafted to provide exact fit and function like the OE gaskets. They are the industry standard for no-retorque designs available in the market. Torque retention is achieved using premium materials with four unique components—core, facing, coating, and armor—and the gasket manufacturing method. The gaskets have been certified to have superior torque retention than other brands. These composite-style gaskets compress during installation to conform to and seal minor surface flaws while yet being able to resist or recover from compression during engine running. The result is a clamping force and a secure seal that lasts for a long time without retorquing. The LaserWeldTM stopper layer design was first developed and proven in collaboration with premier stock car racing teams, is now available in Fel-Pro PermaTorque MLS (multi-layer steel) head gaskets for a wide range of performance and next-generation high-output engines. The unique LaserWeld combustion seal ring reduces head lift, prevents gasket damage, and assures a more robust, more superior combustion seal in many late-model engines.
