Rocker arms are just torqued to specs. The most important thing is that the push rods are installed correctly. They are different lengths. GM recommends new lower intake bolts, and have updated the torque specs on the rocker arms and lower intake bolts.

Exhaust pushrods are longer than intake. Intake valves are closer to the valley of the engine. Torque spec on rocker arms is: 14 NM in. No compression on 3. Sound like you have the push rods in the wrong order.
