The Cometic Cummins 5.9L ISB top-end gasket kit supplies a .072" MLX cylinder head gasket for a 4.100" bore and the seals needed to complete a top-end rebuild. StreetPro kits emphasize quality gasket materials and are offered as top‑end or bottom‑end sets to cover full rebuilds. MLX gaskets include an integrated stopper layer for combustion chamber sealing, improve clamp load around the cylinder while limiting bore distortion and in this case require no additional sealer.
