That happened to me once too (overtorqued). All you have to do is get a drill out kit. They are drill bits but with the threads in the opposite direction. Since the valve cover bolts don't require that much torque, they should come out fairly easily. Make a small hole in the broken part of the bolt and then use the drill out bit to slowly extract it. Make sure that you have someone to collect the metal shavings to prevent them from falling into the head.
