My header bolt in the same spot was also stripped out and I re-tapped the hole and ran a new bolt through. It worked and I have not had any leak issues with it.
 
Either retaping or a heily coil should work just fine.


Welcome to the site. This is a good place for info or just to hang out.
 
Thanks guys! duster maniac, do you remember if you tapped to 3/8ths orsomething else?

I would get the helicoil. It comes with the proper drill bit.

But a 3/8 bolt should also work, can make getting the bolt in a little difficult if the hole in the header flange is off a little.
 
I used a 3/8th machine head hardened bolt. I just threaded it into the hole and it cut it's own threads and holds fine. No leakage.
 
The helicoil kit I just saw at NAPA was $30+ and had no drill bit.
Came with approx 6 coils, tap, plastic insert tool.
Good Luck.8)
 
I had the same problem on my car when I bought it and tried a heli-coil but no matter what sealer I tried I couldn't get it to seal up so I tapped it out to 3/8" and got a double ended stud that was 3/8" on one end and 5/16" on the other so the 5/16" went right through the header just like original.

That`s a great idea, that way the stud fits the header and you can use the same size nuts and/or bolts. I hate having to change out a socket for one odd nut/bolt.
