SOURCE: need torque specs

Valve Rocker Arm Bolt 19 N·m + 30° (14 lb ft+ 30°)
A GM dealer shows me another source, which says 32 Nm (24 lb-ft). Not sure which one is right but they screwed up my car.

Step one: Torque to 11 ft lbs then tighten an additional 90 degrees of bolt head rotation. Some guys don't fuss with the torque specs and just get them good and tight. Either way, be careful, as the heads are aluminum. You do not want to over tighten these bolts
