You must torque to GE specs. It goes as follows:

22 ft-lbs. Go back over all bolts and do 22 ft-lbs.

Next step.

55 ft-lbs. Go back over all bolts and do 55 ft-lbs.

Next step.

82 ft-lbs. Go back over all bolts and do 82 ft-lbs again.

Let the engine sit for a few hours, then torque them down to 82 ft-lbs.

Let the car go through 10 heat cycles. This means getting up to full heat, then cooling down completely. Go through and retorque the studs to 82 ft-lbs again.

Also, use copper spray on your headgasket. Its available at all auto parts stores. You'll need this to ensure sealing of the headgasket.
