Installation and BBT support
Have the installer verify cam timing, piston-to-valve clearance, spring pressures, coil-bind clearance and retainer-to-seal clearance on the actual engine. BBT can help select the supporting parts and arrange installation and calibration.
Applications and compatibility
This part is listed for the following engine and vehicle applications where the Crow camshaft or valvetrain package calls for this exact part number:
- Ford Falcon BA/BF — Boss 5.4L V8
Compatibility is still determined by the complete cylinder-head and camshaft combination; vehicle model alone is not a substitute for checking the required spring, retainer, lock, lifter and rocker setup.
Installation checks
Measure installed height and verify seat/open pressure, coil-bind margin, retainer-to-seal clearance and guide/seal clearance on the actual cylinder heads. Match the spring to the exact cam profile rather than selecting by engine family alone.
