The Cometic Dart MLX head gasket for Hemi Gen3 Iron Eagle blocks with a 4.100 in bore (RHS) incorporates an integrated "stopper" layer for combustion chamber sealing. Its MLX construction increases clamp load around the cylinder without adding bore distortion, providing targeted sealing where the 4.100 in bore and right-side orientation are required.
