The Choate Advantage (Standard on All Sets)
Every pair of Choate 6.4L cylinder heads undergoes an aggressive remanufacturing and blueprinting process designed to solve original factory design flaws:
- Hydraulic Lifter Longevity Fix: We alter the valvetrain blueprint and valve stem heights to completely remove excess preload on the hydraulic lifters, drastically reducing wear and extending lifter life.
- Brand-New Internal Components: Every set is built using brand-new, high-quality intake and exhaust valves, valve springs, durable retainers and locks, valve stem seals, valve seats, valve guides, and pre-installed new injector cups for a proper, reliable fuel seal.
- Optimized Airflow: Valve seats are cut with a precision three-angle profile to optimize airflow through the ports and guarantee an airtight seal.
- Threaded Blow-Proof Plugs: Factory press-fit plugs are replaced with threaded, blow-proof plugs in the top of the head for leak-free peace of mind under pressure.
- Stress-Relieved OEM Cores: Every core is Magnetic Particle Inspected (MPI) for micro-cracks, baked in a furnace to relieve material stress, and shot-blasted before precision machining begins.
- Optimal Deck Finish: Resurfaced to strict Roughness Average (Ra) standards to guarantee maximum gasket sealing capabilities.
- 100% Pressure & Profilometer Tested: Every head is pressure tested at 40 PSI and receives a documented final QC sign-off sheet measuring stem heights, valve recessions, spring pressures, and Ra finish.
