1. Install the pushrod guide plate.
2. Install the push rods.
3. Install the valve rocker arm bearing retainer.
4. Coat the valve stem tip and pushrod tip with prelube GM P/N 1052367 (Canadian P/N 992869) or the equivalent.
5. Install the valve rocker arms.
6. Apply GM P/N 12345493 (Canadian P/N 10953488) threadlocker or the equivalent to the valve rocker arm bolt threads.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
