The Fel-Pro PermaTorqueMLS cylinder head gasket (1177 L) is a multi-layer steel solution built to retain sealing integrity where heads and blocks experience movement or dissimilar materials. PermaTorqueMLS gaskets use strategically located sealing beads to concentrate clamp load around combustion chambers and coolant passages, helping prevent leakage under high cylinder pressures. These are intended for demanding sealing applications in repair environments.
