There isn't a torque spec as these are adjustable. Remove the valve cover. Install oil splash shields on rocker arms. Start the engine. Loosen the rocker nut until it starts clicking. Slowly tighten it just until the clicking stops then tighten 1/2 to 3/4 of a turn. Do this on all 16.
There are no torque specs on 350 Chevy engines. Set solid lifter cams with cam manufacturers backlash specifications, set hydraulic lifter cams with 0 backlash plus 1/4-3/4 turns preload. To my knowledge you don't torque valves, you adjust them.Each one must be done individually.

Take a pushrod and push down on the plunger in the lifter. A hydraulic lifter is spring loaded.
First make sure the cam is turned so that the lifter is on the base circle of the cam, then tighten the nut until there is no backlash plus a half-turn extra.
350 Historically a 396 has valve and lifter problems. A 350, of which I have owned a half a dozen, are great motors.
