PermaTorque MLS Head Gasket Suit ChevLS1-LS6, LH, 4.100" Bore, .053" Compressed Thickness

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.
