shifted base gasket and loose head stud nuts, advice needed

All,

I pulled my 3.0 stock motor due to a leak somewhere on or around cylinder #3. i was thinking it was possibly the Cam Tower to Head. After removing the shroud to look around I cant find any wet spots around that area. however, i did find alot of oil near the base gasket on top bottom and sides as well as the head stud nuts themselves. in addition to that, it seems the base gasket has shifted up about a millimeter or two in relation to the other cylinders. just for giggles, I set my torque wrench to 20 ft/lbs and was able to tighten the nuts on that jug about 1/8 of a turn before I got a click so im thinking they had somehow loosened to about 16ft/lbs?? Waynes book has the torque setting to be 23.5ft/lbs. So, I had a wild idea to loosen all the head stud nuts, re-position the base gasket and torque to factory specs. Then I thought maybe I should pull the rockers, cams and all that and replace the base gasket. Obviously, the first idea is alot less work

I have been running this engine hard at the track for about 2yrs without issues and this just recently popped up. all the dilivar head studs were replaced with steel about 2yrs ago and the motor runs great. im hoping idea #1 is not a bad idea

as always, thanks for the input
