The Cometic .040in MLX cylinder head gasket for Chevrolet Gen-1 Small Block V8 (4.220in bore) uses multilayer stainless steel construction with embossed outer layers coated in Viton and an integrated stopper layer for combustion chamber sealing. MLX technology improves clamp load around the cylinder without increasing bore distortion, requires no sealants or re-torque, and suits round-bore 18/23-degree head applications with steam holes.
