Federal-Mogul's Fel-Pro PermaTorqueMLS multi-layer steel (MLS) head gaskets are designed and manufactured to handle the special needs of big power engines - supercharged, nitrous injected or naturally aspirated. PermaTorqueMLS head gaskets provide the following benefits:

MLS maintains contact pressure between the cylinder head and block.

Seals combustion, oil and coolant despite extreme horizontal and vertical motion between head and block

Distributes clamping loads strategically across the entire cylinder head for optimised sealing.

Fel-Pro PermaTorqueMLS is the ultimate in combustion sealing.
