Cometic MLS head gasket for GM LS Gen-3/4 small-block V8 with a 4.060-inch bore and .045-inch compressed thickness provides a durable multi-layer steel seal for high-output engines. The embossed stainless-steel outer layers are coated with Viton on both sides while the uncoated center shim can be varied for thickness. MLS construction requires no sealants, tolerates aluminum-to-aluminum and aluminum-to-iron mating surfaces, resists corrosion and shearing, and reduces clamp load and bore distortion for improved sealing reliability.
