The Cometic Cummins 5.9L ISB top-end gasket kit provides a .067" MLX cylinder head gasket for a 4.100" bore and the seals required for a top-end rebuild. StreetPro gasket kits are sold as top‑end or bottom‑end sets to support full engine rebuilds while prioritizing quality gasket materials like MLX, AFM, aramid fiber and ArmorClad. MLX gaskets use an integrated stopper layer for combustion sealing and help improve clamp load distribution without added bore distortion.
