If you don't use TTY bolts, you should (be crazy not to) retorque after heat cycling.

The stock head gaskets do not require retorque. But Like Brian said it doesn't hurt to. I would just do the initial torque, wait overnite or next day, and retorque one bolt at a time. Back em off 1\2 turn each, then retorque to 85lbs. but do each bolt in order one at a time..
