Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 features a .086" compressed thickness for 4.100" round bores and 18/23 degree heads. Constructed from multiple embossed stainless steel layers with Viton coating on the outer faces, it resists corrosion and rebounds under load. The design seals aluminum or cast-iron pairings without sealants, evens load distribution across the sealing area, and helps reduce bore distortion under clamp load.
