I think standard size would be 14mm x 1.5 thread pitch but I could be wrong.

All you have to do to get the right answer is GOOGLE for THE NUMBER ON THE PLUG like:
WHAT SIZE IS C7HSA SPARK PLUG: You will find they are 10mmx1.0 pitch

After reading some of my older posts looks like my BB kit is the 80cc when I bought it it came with the kit but now I see on ebay they dont sell BB kit with the head on most since I stupidly stripped out my spark plug hole can I just put my stock head back on it looks the same as the one I have on now will this help me alot of hassle of ordering just the head since it just sitting in my parts shelf ..I did reading and sounds like I will be ok doing that just want to make sure before I start the repair ..thanks for helping as I have not work on mine in a while ..

What I would do is after finding the correct size, spend some time with a spark plug chart and pick out a similar plug the next size bigger threads. Then go borrow a spark plug tap that size to run in the bad hole.

I have done it before quite a few years ago and never had a problem. Those heads are almost as soft as lead solder, they tap easy and also strip out easy. When I put a plug in an aluminum engine I grip the ratchet right behind the head, and not the end of the handle and go just a fraction of a turn past snug. (those shorty ratchets are nice too if you don't put a lot of pressure on them) all it needs is enough tight to make a nice mark all the way around on the crush washer. If you flatten that washer out completely you are chancing a stripped thread. crushing it half way would be fine.

Yes you can use the old head, then since you have the stripped head off you can fix that one.
