The Cometic MLX head gasket for Hemi Gen3 Iron Eagle blocks with a 4.100 in bore (LHS) incorporates an integrated "stopper" layer to seal the combustion chamber. Its MLX construction boosts clamp load around the cylinder without increasing bore distortion, making it suitable for applications requiring the 4.100 in bore and left-side gasket.
