stripped threads for valve cover bolts

I found out that one of threads for the valve cover bolts in the head is stripped. Bolt just spins and spins. What can I do to fix the problem? Does heli coil make anything that small? Retap? If I retap, can I still use the rubber gasket washer? Does anyone know what size the bolt is? it's the short valve cover bolt for a z6 head.

yes there are heli coils that small for that job. I bought a set of heli coils awhile back from a auto parts store. I think it was Napa(not sure though)
