Fel-Pro PermaTorqueMLS cylinder head gaskets are engineered to retain sealing integrity where dissimilar head and block materials create movement. The multi-layer steel design uses strategically located sealing beads around combustion chambers and coolant passages to concentrate clamp load and reduce leakage risk under high cylinder pressures and increased head movement.
