If you’re making 700HP+ in your 2007.5-2018 Dodge 6.7L Diesel upgrade to Hamilton Cams 07-G-6.7 Fire Ring Head Gaskets. Fire ringed heads provide a much stronger seal and help eliminate the normal head gasket problems found on higher boost levels. This kit features a standard thickness gasket with the O-rings included.

6.7L gasket .046 thick , 4.560" wire O.D.

1.25mm gasket, radiused grooves should be .019 inch in the block and head or .039 inch-.040 inch if only using one groove in either the head or block

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 we suggest cutting grooves in both the head and block.  We suggest a radiused cutter for all installations. Studs are a must for proper clamp load. Our rings are made from .105 inch wire and are 4.560 inch in diameter. When using our competition gasket, studs are a must. 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. We 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.
