Cometic's MLS head gasket for Ford 335-series 351 Cleveland (4.100" bore, .062" compressed thickness) uses multiple embossed stainless steel layers with a Viton coating on the outer layers to resist corrosion and heat. The uncoated stainless center shim accommodates thickness needs while the multilayer construction rebounds under load to maintain sealing without sealants, making it suitable for high-output engines and mixed-material head/block combinations.
