one of my friends wife's calls up almost in tears, hes out of town and she tried to move his corvette in the drive way and the engine started making a hell of a noise so she called me, a few minutes of inspection, results in finding his corvette has a spark plug dangling on the end of a plug wire, it backed out, over time, and the last couple threads in the head are not perfect, so I go get a spark plug thread chaser, coat it with anti-seize to collect any small chips , and re-clean the threads then add some oil to the cylinder thru the open plug hole,so that it will blow out when she starts the engine and carry any micro crap that might be in the cylinder with it as it exits under pressure,I then assure his wife that although its going to smoke and be noisy for a few minutes that's nothings wrong, after running it for 30 seconds I have her tun it off and I gap the plug, coat the threads with anti seize and carefully re-install it, we test fire the engine and ITS JUST FINE!
we then throw a bunch of engine cleaner around the engine compartment to clean the oil spray up and hes back to having a good car, all this time the WIVES (MINE AND HIS) are talking about how stupid husbands are because of caring so much about CORVETTES vs THEM, but hey I brought the wife so she doesn,t think IM screwing around and to have no doubt I was not doing a darn thing but helping with the car, while my friend was out of town,.
keep in mind that different brands of plugs will have different lengths that can be critical with ignition wire to header clearances
theres several ways to repair stripped spark plug threads in a cylinder head read the linked info carefully, EACH LINK PROVIDES ADDITIONAL USEFUL INFO
IF youve stripped your spark plug threads, its more than likely the result of not using anti-seize on the threads or cross threading the plugs during the install, I know you most likely don,t want to hear this, but I,m telling you what will be best in the long run, to do the job correctly youll want to pull the cylinder head and take it to a local machine shop, where they can inspect and decide what needs to be done, any other route is guess work

Assuming the heads ALUMINUM, it makes it much easier but theres several route that can be taken,you " might" be able to heli-coil repair the threads but the correct repair will require the head being removed re-welded drilled and re-tapped
the other option involves drilling and tapping the head for a repair insert
