Fel-Pro 1161 L PermaTorqueMLS Engine Cylinder Head Gasket

In this box, you get the Fel-Pro 1161 L PermaTorqueMLS head gasket, specifically designed for the demanding conditions of performance engines. This gasket is built to handle the high cylinder pressures and the movement that can occur between dissimilar materials, like aluminum heads on a cast iron block, which is common in Chevrolet's Gen III V8 engines, including the LS-1 and LS-6.

Fel-Pro uses a multi-layer steel (MLS) construction for this gasket, which is a well-built approach for sealing performance applications. Strategically placed sealing beads are incorporated 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 under high stress. This design is particularly useful when dealing with imperfect sealing surfaces, a common challenge in real-world engine repairs.

Keep in mind that this gasket is intended for performance use and is not designed for vehicles with emissions controls.
