Fel-Pro 1161 R PermaTorqueMLS Engine Cylinder Head Gasket

If you're rebuilding the top end of a Chevrolet V8 Gen III engine, like an LS1 or LS6, a reliable head gasket is crucial for sealing combustion pressures and coolant. The Fel-Pro 1161R PermaTorqueMLS head gasket is built to handle the demands of these performance engines, ensuring a strong seal even with the movement and scrubbing that can occur between dissimilar materials like aluminum heads and cast iron blocks.

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 very effective seal that prevents leaks. Fel-Pro designs these gaskets with imperfect sealing surfaces in mind, making them a solid choice for the real-world repair environment.

It's important to note that this specific gasket is not intended for use in emissions-controlled vehicles. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures when installing head gaskets.
