The Cometic MLX head gasket for GM Gen-V small-block V8 variants L83/L8B/L82/L84 is a 3.875in bore .052" MLX design that uses an integrated stopper layer for improved combustion sealing and enhanced clamp load around the cylinder without increasing bore distortion. Coated with Viton on both sides, this gasket offers a multi-layer solution requiring no sealants or re-torque.
