Stripped header holes, need advice

[AtwoodDon at aol.com]

Keith, a helicoil will certainly work assuming you can find someone with  the 
correct size(s).  I have successfully drilled and tapped the header  bolt 
holes, just go slow, take your time, etc.  I also suggest making sure  you don't 
drill too deep on the exhaust port flange, just deep enough to get  necessary 
threads.  Also, a flat bottom tap will let you get deeper with  the threads 
than a standard tap that goes all the way thru.

I have a Webra 1.45 that has had the threads  stripped out of the screw holes 
that are used to mount the header. I need some  advice on the best way to fix 
this.  Drill out and re-tap bigger?  Heli-coil? Another solution?
 
Not really sure what the best solution is. I'd  appreciate suggestions if 
anyone knows what the best approach is.
 
Thanks,
Keith Black
