    SERIOUS RACING ENGINE UPGRADE

    244HV-B

    268°/280° | 11.0mm/11.0mm Valve Lift

    Note: This kit is shimless and requires a qualified trades person to machine and setup the head for best results.

    - Intake requires a 45.10mm-45.40mm Tip height
    - Exhaust requires 49.00mm-49.30mm Tip height

    These tip heights will get valve clearances close, machine the tip of the valves to set the correct clearances. Best results are done using a torque plate.

    244HV-A

    Designed for high-boost, high-RPM racing, this kit features Kelford's shimless bucket package and ultra-clean Silicon Chrome spring steel for excellent fatigue resistance. The high-frequency springs minimize surge at elevated RPMs, while the titanium retainers eliminate the need for shims. Ideal for maximizing RB engine performance.
