Each cylinder head is crafted to your specifications, delivering a ready-to-bolt-on unit that meets high standards of quality and durability.

Comprehensive Build Process

Every head starts with an intensive cleaning and refurbishment process to restore and enhance its condition:

• Hot Tank Cleaning: Thoroughly removes oil, grime, and contaminants to prepare the head for further work.
• Sand Blasting: Eliminates corrosion and debris, reveals a uniform satin aluminum finish, and improves the overall aesthetic appearance.
• Remove, Rethread, and Reinstall Oil Port and Freeze Plugs: Ensures clean oil passages and replaces aged freeze plugs for optimal sealing.
• Remove, Ream, and Replace Valve Guides: Installs high-quality Supertech bronze valve guides, correcting typical wear found in older DET heads on both intake and exhaust sides.
• Multi-Angle Valve Job Upgrade: Enhances valve seat profiles by cutting multiple angles and a radius, improving airflow through the 90mm combustion chamber.
• Surfacing: Resurfaces the head with a poly-crystalline diamond (PCD) tool to ensure a perfectly flat and smooth sealing surface.
• Replace Valve Seals: Installs new Viton valve seals to prevent oil leakage and improve valve performance.
• Assembly: Carefully installs valves, springs, and retainers.
• Set Rocker Level: Adjusts rocker levels to the cam using your existing guides and shims to achieve precise valvetrain setup.
