Brand New Cummins ISB 6.7 24 Valve LOADED Enhanced Cylinder Head with Firing Ring They are better than OEM quality containing 5% more nickel content in the casting material. This additional nickel content prevents the cylinder head from cracking in between the valves. Additionally, the coolant passages have been enlarged by 30%, and inner ribs have been reinforced to reduce heat stress. If you have been a victim before of a cracked cylinder head, you know just how costly that it can be! Don't take the chance by buying an OE reman cylinder head that is bound to crack again. Upgrade with our Enhanced Performance Cylinder head and enjoy the peace of mind while hauling across the country! In addition to this, the cylinder head has a stainless steel fire ring machine right into the deck of this cylinder head to avoid any chance of blowing a head gasket, which is a common failure in engines that are tuned to higher horse power. This allows you to turn up the heat and pressure with the peace of mind knowing that you have the heaviest duty head on the market under your hood. This performance cylinder head is an upgrade from the standard cylinder head. On top of the interior upgrades to the actual casting itself, the intake valves in this cylinder head have all been upgraded to inconel valves. This major performance improvement increases the capacity of the valves to endure higher temperatures as well as heightened pressure.
