The Cometic MLX head gasket for GM LSX Gen‑4 small block V8s is a .060 in multi-layer cylinder head gasket with a 4.165 in bore for RHS heads. MLX construction uses an integrated stopper layer for combustion chamber sealing and embossed outer layers coated with Viton for heat resistance. The design improves clamp load distribution without raising bore distortion and seals reliably without additional sealants.
