The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (.062in, 4.100in bore, round bore) uses multiple embossed stainless steel layers with Viton-coated outer faces and a center shim layer. MLS construction provides strong sealing for high-output engines, withstands shearing between different head/block materials, resists corrosion to elevated temperatures, and requires no sealants while improving load distribution.
