Looking at the service manual, the valve on your engine are hydraulic and need only be torqued down to 40 ft lbs, Is this not matching what you have?
If not then the best way to adjust them is to do it while running. With it running, slowly loosen each rocker until it starts to make noise, then tighten till it stops and add 1/4 turn.

There is no need to replace the nuts if there is no damage to the old ones.
