The Cometic MLX head gasket for Hemi Gen3 Iron Eagle blocks with a 4.275 in bore (RHS) uses an integrated "stopper" layer to seal the combustion chamber. The MLX construction improves clamp load around the cylinder without increasing bore distortion, providing a focused sealing solution for applications that specify these MLX dimensions and sealing features.
