Valve adjustment - Jam nut torque spec?

I'm doing a valve lash adjustment on my 94' LS and I can't seem to find the torque spec for the jam nuts. Anyone know them?

Thanks

if im not mistaken i think there is no torque spec for the lock nut, because if you tighten it your tolerances will be off. thats why they use a lock nut.

not sure if you torque it down, i think you just tighten the nut until there is no up and down play and then turn it 1/2 or 1/4 turn and your good. correct me if im wrong
