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.
Hey guys,
Does anybody know the torque spec for the actual stud? (the one that goes in the block?
(yes, I broke one...)
