The Cometic MLX head gasket for Dart Hemi Gen3 Iron Eagle blocks is a multi-layer cylinder head gasket specified for a 4.000 in bore and .040 in thickness (left-hand side). MLX gaskets employ an integrated stopper layer to seal the combustion chamber and improve clamp load around the cylinder without increasing bore distortion, helping maintain a reliable seal under high clamping pressures.
