Fel-Pro® PermaTorque® MLS (multi-layer steel) head gaskets provide torque retention and extra strength to support lightweight aluminum casting designs.Developed to seal in the repair environment, under these less than factory-perfect conditions, these MLS gaskets have many unique features that are more forgiving than other designs and accommodate surface irregularities up to 60 Ra (360 Rz).

Features include:
  • Full-hard stainless steel that maintains its shape despite thermal expansion, and resists the scrubbing action between head and block
  • Precision-engineered
  • An exclusive extra-strong "stopper" layer incorporated to provide a superior primary combustion seal
  • Special rubber coating, specifically formulated for the engine rebuild environment, is more forgiving of surface finish requirements
If the vehicle engine was equipped with an MLS gasket from the factory, the Fel-Pro replacement will be a PermaTorque MLS gasket.
