SOURCE: needed torqur spec on rocker arms on 1994 gmc

There is no torque spec for rockers. You tighten until there is no backlash, then preload another 1/4 to 1/2 turn. With #1 at TDC on the compression stroke, you adjust #1 by this procedure. You can also adjust intake valves on #'s 2, 5 & 7 as well as exhaust on 3's 1, 3, 4 & 8. Then rotate the engine until #6 is TDC on compression stroke and adjust intakes on #'s 3. 4. 6 & 8 and exhaust on #'s 2, 5, 6 & 7. Good luck.

What is the torque specs for the rocker arms and head on a 1988 GMC SIERRA V-8 SHORT BLOCK?
everything you need below.
NOTE: Rocker arms arent under torque. You can google the process to adjust them, but just enough to take the slap out.... too tight and the valves will go stupid.
