The .020-over version of Hamilton's 6.7L fire ring head gasket. The added thickness over the standard gasket is the usual route to recovering piston-to-valve clearance when a performance camshaft will not quite drop in, while retaining fire ring sealing for high cylinder pressure.

Key Features

  • .020 inch oversize thickness
  • Fire ring construction for combustion sealing under high boost
  • Commonly used to regain piston-to-valve clearance during a camshaft install

Fitment

  • 2007.5-2018 Dodge and Ram 6.7L Cummins 24-valve

Machining and Installation

  • High-strength studs are required to achieve proper clamp load
  • Cylinder head must be within .003 inch end to end; machining both head and block is best practice
  • If the block is not surfaced, clean the deck with a 320 grit or finer stone
  • Always use a .120 inch radiused cutter for groove formation
  • Torque to 130 ft-lbs at startup, hot retorque at operating temperature, then retorque again before applying full load or RPM
  • Each retorque reduces valve lash, so readjust as needed
  • Never exceed the fastener manufacturer's torque limits
