The 2000 Chevy Impala 3.4 liter engine rocker arm bolt torque specification is 45 pounds. The rocker arm bolts should be torqued in 15 pound intervals.
The rocker arms need to be adjusted, they are not set to a specific torque, they use self locking "crimp" nuts to hold the adjustment, these nuts should not be used over to hold the adjustment replace them.. With the lifters fully "pumped" up tighten the rocker arms to "zero" lash, the turn them in an additional 3/4 turn, you are done.

you dont torque rocker arms, they are hydralic they are adjusted by running the engine at idle with valve cover off back off the rocker nut till you hear them clicking, then tighten them till clicking stops, then 1/4 turn more, each one is done separately, you need to use some sort of shield to keep the oil from pumping out all over every thing because it can get a bit messy
