Cometic MLS cylinder head gasket for Chevrolet Gen-3 Inline 6, sized for a 4.125 in bore with a 0.066 in nominal thickness to provide high-output sealing. Multiple embossed stainless steel layers with Viton coating on the outer faces and an uncoated shim center resist shearing between dissimilar metals and require no sealants.
