The Ultimate in Combustion Sealing for High-Performance Engines
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. The new head gaskets feature 3.425-inch bores and offer a compressed thickness of .055-in. for compressed volume of 8.3 cubic centimeters.
Engineered specifically for these applications, the new Fel-Pro PermaTorqueMLS gasket set (p/n 1153-1) provides the robust combustion seal needed to contain extreme combustion pressures and temperatures common to naturally aspirated, turbo/supercharged and nitrous-equipped performance engines. Each gasket is composed of five layers of fully-hardened stainless steel, precisely engineered sealing beads and a sophisticated stopper layer.
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 optimized sealing
