2007.5-2018 Cummins Standard Fire Ring Gasket (07-g-6.7)

Fits

When you start making over 700HP in your 2007.5-2018 Cummins 6.7L you will want to upgrade! This Gasket will stamp out head gasket problems at high boost levels and produce a much stronger seal. This standard, high-quality gasket includes the o-ring wire. 

Part Number: 07-g-6.7

• Stamp our head gasket problems
• Much stronger seal
• Includes o-ring wire

• For best results please have your head and block machined prior to installation for flatness. 
• For engines under 800hp, cutting grooves in the head or block is adequate, but for higher horsepower engines it is suggested to cut grooves in both the head and block.  It is suggested a radiused cutter for all installations. 
• Studs are a must for proper clamp load. 
• Be sure to use a liberal amount of lubrication on the nut, washer and threads of the studs so that every stud sees similar clamp load. If lubrication varies stud to stud, clamp load on gasket will not be equal and can allow gasket failure.  Never under any circumstances, should you take a fastener beyond the limits listed by the manufacturer. There is a huge amount of potential energy in fasteners at full torque. Suggest 130 ft/lb of torque for initial startup. Get engine to operating temperature, then retorque while hot. You should check valve lash after each torque sequence as re-torques crush the head gasket more and will make valve lash less. It is always a good idea to re-check torque at least one more time before you take engine to full load/rpm.
