Here is a suggested updated torque spec for this engine's rocker arm bolts;

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

Hope this helps

You don't. They are non-adjustable hydraulic lifters. GM's spec for torque on the rocker arm nuts: Tighten the valve rocker arm ball studs to 47 N·m (35 lb ft). Once the valve rocker arm nuts are installed and properly torqued, no additional valve lash adjustment is required.

Rockers don't get torqued. Adjust each just after the valve closes plus a bit more turning by hand. Tighten till the pushrod can just be turned with your fingers. Still the best way to do final adjustment is with the engine running....Loosen each rocker till it clatters, then turn down slowly 'till the clattering stops, then a half turn more. Keep the opposite cover on as using this method will make a mess on the ground (oil). Adjust each rocker the same way.
