If there is a local Honda dealer around, check with them.

There is a company called "TIME SERT" and they make replacement thread for automotive head spark plug holes. The kits are cost prohibitive but you can usually find an engine repair or machine shop that can install one for you.
TIME SERT is far superior to Heli-Coil and will hold through the rigors of combustion when all the others pull out.
