Cometic MLS head gasket for GM LS Gen-3/4 small-block V8 with a 4.160-inch bore and .051-inch compressed thickness supplies dependable multi-layer sealing for high-output applications. Embossed outer layers are stainless steel coated with Viton while the center shim is uncoated stainless steel to allow thickness variation. This MLS design requires no sealants, resists corrosion and shearing between dissimilar metals, and helps conform load across the sealing area to limit bore distortion.
