stripped exaughst head threads

How can I fix these threads? I over torqued while tightening the manifold and stripped the threads. Can I just tap out a bigger hole? Thanks

Helicoil it. You might have to put in a US size bolt instead of the 10mm shaft diameter (14mm head) bolt that was in there previous. Aluminum is a pleasure to drill into.
