This Cometic MLX head gasket for the Chrysler 6.4L Hemi (4.150" bore, .040") uses an integrated "stopper" layer to improve combustion chamber sealing. The MLX design enhances clamp load distribution around the cylinder without increasing bore distortion, supporting reliable sealing under demanding conditions while preserving engine geometry.
