Cylinder head bolts are done in 3 steps. Step 1 - 20 ft.-lbs
Step 2 - 50 ft.-lbs
Step 3: Tighten an additional
90 degrees.
Lifter guide plate bolts 18 ft-lbs
Rocker arm shaft bolts 40 ft-lbs
Hope this helps.

Torque specs 2003 olds silhouette rocker arm 3.400


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

How do I adjust the valves on a 1998 old bravada 4.3 vortec


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.
