The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.045in uses multiple stainless steel layers to provide durable, resilient sealing. Embossed outer layers coated with Viton offer heat and sealing resistance; the uncoated shim layer allows thickness adjustments. This MLS gasket seals aluminum heads to aluminum or cast-iron blocks without sealants and helps conform load distribution, reducing clamp-induced bore distortion.
