Fel-Pro 1162 L PermaTorqueMLS Engine Cylinder Head Gasket

If you're rebuilding the top end of a Chevrolet V8 Gen III engine, specifically an LS1 or LS6, a quality head gasket is crucial for sealing combustion pressures and coolant. The Fel-Pro PermaTorqueMLS head gasket is built to handle the demands of these performance engines, where cylinder pressures can be significantly higher and the movement between dissimilar materials like aluminum heads and cast iron blocks needs to be managed.

This gasket uses a multi-layer steel (MLS) construction, which is a modern approach to sealing. It features strategically placed sealing beads around the combustion chambers and coolant passages. These beads concentrate the clamping force from the cylinder head bolts, creating a strong seal that helps prevent leaks even when the engine experiences significant scrubbing and movement. Fel-Pro designs these gaskets with imperfect sealing surfaces in mind, making them a solid choice for the real-world repair environment.

Keep in mind that this gasket is not intended for use in emissions-controlled vehicles. Ensure you have the correct tools and follow manufacturer procedures for installation to achieve the best seal.
