Checked the P&W Mtce manual today.  exactly the same info as the Overhaul.   No reference to any subject torque value.
 
Also checked FAA AC 65-12, with a very comprehensive and detailed section on valve systems and processes including numerous pages on adjustment.   They make no specific recommendations on torque values for adjustment nuts.  They do make a reference to fastener torque in general stating that the manufacturers recommendations are to be followed.  In this they give, as an example, the rocker cover hold down nuts used
on many radial engines.  These are light aluminum alloy and there has always been a history of over tightening, warping and subsequent leakage.
 
As I mentioned earlier the jamb nut securing method has been around forever and is highly effective.  The prime example of this is two plain nuts tightened to each other on a threaded shaft, bolt or similar.  In this case the rocker arm serves as the second nut.
 
My diatribe for the day !!!!!!!
