dont worry about why, just take another nut with same threads and tighten it on top of the existing nut
22 ft lbs torque on the rocker arm nuts is all that is required.
With the valve fully closed and the lifter fully at the down position, tighten the adjusting nut until there is no up and down travel in the push rod. Then tighten the adjusting nut 1/4 turn. This is only if you have hydraulic lifters. Tighten the rocker studs to 50 ft/lb of torque. These are the bolts holding the rocker assembly in place.
With the engine at operating temperature back off the rocker arm until it slightly clatters. Tighten it down slowly until the valve is quiet and then tighten it 3/4 of a turn more.jd

It's not necessary to run the engine. With #1 at TDC, you can set 1, 2, 5, and 7 intakes, and 1, 3, 4, and 8 exhausts. Rotate engine one revolution (#6 TDC) and set the rest. If it's a hydraulic cam, tighten the rocker nut until there is 0 up and down movement in the pushrod, then tighten an additional 1/2 turn. For solid cams, tighten rocker nut until specified backlash is achieved.

Most Chilton's, Motor's, or Haynes book should include detailed instructions on how to adjust the valves. With the engine running, back off the rocker nut until it clatters. Tighten it back down until the clatter is gone then tighten it 1/2 turn more. Any tighter will possible cause it to run rough or miss.
