7 ft-lbs isn't far from the actual spec; it's listed in the Beisan Systems double VANOS repair article. With an accurate inch-pound wrench, you feel the "click" when you tighten the nut to just a little bit beyond the point where it bottoms out on the threaded stud.

If the valve cover gasket was previously replaced, it's possible that whoever did the work overtorqued and weakened the studs in the cylinder head. Fortunately, replacements aren't expensive.

Also, remember that a torque wrench is most accurate in the middle of its range, and it is least accurate at the limits of its range. A 5 to 45 ft-lbs range, for example, isn't the best choice.
