Cometic’s MLS head gasket for GM LS Gen-3/4 small-block V8s is a multi-layer steel gasket built for high-output applications. With a compressed operating thickness of 0.080" and embossed stainless layers coated with Viton, it seals reliably without additional sealants. The center shim layer is uncoated stainless steel and the MLS construction rebounds to resist corrosion and shear between dissimilar head and block materials, offering durable sealing for Gen-3/4 LS engines.
