What are the torque specications for rocker arms on a 2000 Pontiac Montana 3.4 liter engine?

The specification calls for initial tightening to 14 ft/lbs of torque, then GM uses a torque angle specification of 30 degrees from there. This requires a special tool that mounts between the socket and the ratchet. It is indexed and one end is held in place with a clamp. The pointer is then "zeroed" and the bolt is tightened slowly until the pointer moves 30 degrees as measured by the special tool. Be careful...over tightening these bolts can pull the threads out of the cylinder head.
