Heli-coil How-to

["cruznmd" <racuti1@xxxx>]

Ok. I worked on my other valve head until 11:30 last night. I have 
the timing cover cleaned up, new crank seal installed. Valve cover 
cleaned up.

The head went badly. As with the other head, someone long ago, 
snapped off one exhaust stud. I had to dremel off one bolt. The 
others snapped off. I did manage to extract all the studs but the old 
broken off one. One stud welded itself to the exhaust manifold badly. 
When I pried the manifold off the head, I thought the stud was 
staying fixed in the block and the manifold was slipping off of it, 
but what really happened, was the stud remained in the manifold and I 
ripped the threads out of the head.

Now I don't care about the manifold. It's toast and I have a like-new 
set. I want to install a heli-coil in the head because I don't think 
there's enough metal left to tap it out.

Anyone know how to do this?
