Another helicoil, or a timesert, or head off, weld, redrill and tap new hole. Risk with the latter method (while undoubtedly the most permanent if done right) is the head may warp a bit from the heat and require some addtional work to re-true it (and the the valves/ seats etc). I'd recommend speaking to a professional.

I used a Timesert in my 750. I'm not a big fan of Heli-coils and like the Timesert a lot better.
