The Cometic MLX head gasket for Cummins 5.9L ISB CR applications provides a .067" cylinder thickness for a 4.100" bore and uses MLX construction with an integrated stopper layer to improve combustion chamber sealing. Coated on both sides with Viton and built from multi-layer stainless materials, it increases clamp retention without increasing bore distortion and requires no sealants.
