The simple answer is there is no tq spec. You are adjusting preload. Go to zero lash, adj preload, lock down.

As stated above, they're not torqued down. Depending on the position of your cam, some rockers will be tighter than others when you pull the valve covers. Shoebox has a good description of the process here:

I don't remember on stockers, but I know if I take my covers off with the car cold some of them have slack (ones with the valve closed) Start it and see if any are real noisy. May just be normal.
