Product Description
PermaTorqueMLS head gaskets offer a wide range of benefits, including:
* Strategically placed sealing beads that help eliminate leak paths.
* Extra-strong stopper layers that provide superior primary combustion sealing (where applicable).
* Full-hard stainless steel material that maintains its shape despite thermal expansion and scrubbing between the block and head.
* A unique, application-specific coating that enhances sealability.
What’s more, Fel-Pro PermaTorqueMLS head gaskets provide the torque retention required to maintain positive contact pressure between head and block over the life of the repair.
