HELP! Torque settings

Im doing a head gasket on my girlfriends car, its a 91 mazda sentia (929/ms9) with JE-ZE 3.0L V6 but cant find the head torque settings for it anywhere. I rang mazda, apparently they dont know and theres no repair manual made for them, cant find it anywhere on the net either. Any suggestions on what to do in this situation? Would rather not guess
