Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 provides reliable sealing for high‑output Chevy engines. It fits a 4.165 in bore and is offered in a nominal 0.056 in thickness with a compressed operating thickness of 0.036 in, making it suitable for demanding rebuilds without sealants. Built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim layer, it resists corrosion, accommodates thickness variation, and requires less clamp load to reduce bore distortion.
