Cometic MLS-5 head gasket for GM LS Gen-3/4 small-block V8 engines with a 3.910-inch bore and .060-inch compressed thickness provides a resilient multi-layer seal for high-output builds. Embossed stainless-steel outer layers are coated with Viton and the center shim is uncoated stainless steel to permit thickness choices. MLS construction needs no sealants, tolerates aluminum-to-aluminum or aluminum-to-iron mating, resists corrosion and shearing, and helps distribute load to minimize bore distortion.
