The Cometic MLX head gasket for GM LSX right‑hand side features a 4.200 in. bore, .052 in. thickness and parallel cooling passages. MLX gaskets use an integrated "stopper" layer to improve combustion chamber sealing and the gasket design helps improve clamp load around the cylinder without increasing bore distortion, supporting consistent sealing for high‑duty engine builds where reliable combustion sealing is required.
