6.4 Powerstroke Cylinder Heads

6.4 Powerstroke Cylinder Heads 

Built to Survive What Stock Never Could

Your 6.4's factory head gasket design is the #1 point of failure under boost, towing load, or a tune. We fixed that. Every head we ship is fully O-ringed to increase clamping pressure on the head gasket, locking it in place and eliminating the blown head gasket cycle for good — no more coolant in the oil, no more overheating, no more guessing.

Perfect for street trucks and heavy towing setups — anywhere the factory gasket gets pushed past its limit, this head holds the seal.

What's Done to Every Head:

• Precision O-ringed for increased head gasket clamping pressure and a bulletproof seal under high cylinder pressure
• All new valve guides — no worn-out tolerances, no oil consumption issues
• All new valve seats, cut true and sealed for a bulletproof compression seal
• All new valve seals to keep oil out of the combustion chamber
• Upgraded valve springs for improved durability and consistent valve control
• Complete valve job — every valve hand-lapped and pressure tested
• Surfaced true and flat on precision machining equipment
• Finished in heat-resistant paint to fight corrosion and handle the heat cycle abuse these engines see

Beyond gasket integrity, a properly set up head means better airflow and improved fuel atomization — better combustion, better power delivery, better efficiency. This isn't a reman head pulled off a shelf and repainted. Every head that comes through our shop is machined in-house on our own equipment — the same shop we bought specifically because we weren't satisfied with what was available on the market. If it doesn't meet our standard, it doesn't go out the door.

Built for guys running a tune, towing heavy, or done replacing head gaskets every 60K miles. This is the last head gasket job you'll ever do.
