You cannot use the old bolts to retorque the heads. They are torqure to yield bolts. You must get new bolts.
Torque for valve cover bolts is 7 to 10 ft. Lbs . Tighten the bolts in a criss-cross pattern .

Go to Autozone or a NAPA parts store and buy a Haynes Manual for the vehicle. It will tell you all of the torque specs you need and the tightening pattern.

You more than likely have a valve cover gasket leaking. You can try tightening the bolts holding the valve cover in place to 20 lb/ft of torque, (do not over-tighten) and see if that stops the leak. If not, you will have to replace the gasket.
Work from center out alternating, snug up, torque to 55in pounds or 4.55 ftlbs.
Breakaway torque is the torque required to start the initial movement, in the loosening direction, of a bolt, screw, or nut from its (non−loaded) at rest position with the locking element engaged. Tightening torque is the torque necessary to move the bolt, screw, or nut along its threaded length in the tightening direction.
Ineed the torque sequence and tightening specs for a 92 GM 3800 intake.
The correct torque spec is 85 INCH lbs.
The torque is 89 inch pounds or 7.41 foot pounds. You should never reuse a transmission gasket. If you are doing work on the transmission, replace the filter, it usually comes with a new gasket.
the valve cover gasket is loose and or worn out, try to re-torque the valve cover or replace the gasket
