Install the Crankshaft TDC Timing Tool.

NOTE: Camshaft timing slots are off-center.

NOTE: Position the camshaft timing slots below centerline of camshaft.

Install the Camshaft Holding Tool and the Adapter for 303-577 on the front of the RH cylinder head.

NOTE: Leave the top 2 Camshaft Sprocket Holding Tool clamp bolts loose.
