You may be able to go bigger but you my also end up cracking the head. I would remove and rethread the hole for a helicoil of the same size and see if it stays tight(er). Use locktite as a precaution. Only go bigger if you have too.
If it doesn't then I would seriously consider a new head. Eventually it's going to work loose again and possibly crack the head or launch a spark plug through the hood into outer space.

Have it evaluated by a mechanic. Helicoil works sometimes, but at best it's a band-aid repair, meant to get you to a garage, nothing more. Your cylinder head needs to either be re-tapped to accomodate a spark plug with a larger thread diameter, or it needs to be replaced. The loud THUNK you hear next time you're driving followed by the blatty sound and gassy smell will be your spark plug finally parting company with the cylinder head...let your fingers do the walking...

I would forgo the bucks and get a new head, have it serviced and put it on. Usually a salvage yard will have the one you need and guarantee it is OK. You might not have to have it serviced.
Helicoils are good to put in a vehicle you are going to sell. The temp, compression, time will loosen up the best heli-coil

your drill size was wrong the last time you helicoiled it. Helico's rarely strip, if ever. are u overtightening your plugs? try antiseize after u fix the 2nd helico installation. good luck. try a torq wrench next trime too.
