Can you fix a stripped bolt hole?
The complete repair for stripped threads is to use a coil-type thread insert. These inserts will give the bolt hole completely new threads which accept the size of the original bolt. In order to use inserts, you must drill the damaged holes slightly larger so that it can take the thread insert.
How do you Retap a threaded hole?
Use a rethreading tap to restore threads on nuts or threaded engine component holes. Don’t try to rethread the entire bolt, hole or nut in one operation. Insert the rethreading tap or die and rotate a few turns, then back it off a full turn. That will dislodge the debris from the teeth.
Will a cross threaded bolt hold?

What should I use to clean head bolt hole?
Once the offending head bolt hole has been repaired, you should clean the other holes. But don’t use a normal tap. Normal thread taps remove block material that will only increase the chances of pulling threads in other holes. ARP makes a thread cleaning tap that is designed to sweep the threads but not remove metal.
