Comprehensive Build Process
- Hot Tank Cleaning: Thoroughly removes oil and grime, ensuring a clean foundation.
- Sand Blasting: Revitalizes older heads by removing corrosion and debris, restoring a uniform satin aluminum finish for improved aesthetics.
- Removal and Replacement of Oil Port and Freeze Plugs: Fully cleans oil galleys and replaces freeze plugs to maintain optimal engine health.
- Shimless Valves: Replace traditional shim setups to prevent wear and damage at high RPM, enhancing reliability.
- Stage 3 CNC Porting and Polishing: Advanced CNC porting developed on a Superflow 600 flow bench maximizes airflow through optimized ports and valve seats.
- CNC 90mm Combustion Chamber: Opens combustion chamber to reduce detonation hotspots and improve valve breathing by removing squish areas.
- Valve Guide Services: Removes, reinstalls, and reams valve guides, replaced with durable Supertech bronze guides for enhanced longevity.
- Multi-Angle Valve Job: Incorporates up to five angles plus radius to improve flow efficiency in conjunction with the 90mm chamber.
- 1/2″ Head Stud Machining: Enlarges stud holes to accommodate 1/2″ head studs with machined dowel pin locations for 16mm dowels.
- Precision Surfacing: Resurfaces the head using poly-crystalline diamond (PCD) tools to ensure a perfect sealing surface.
- Valve Seal Replacement: Installs new Viton valve seals for reliable sealing and longevity.
- Assembly and Valve Lash Setting: Assembles valves, springs, and retainers, setting lash precisely to camshaft specifications for optimal performance.
