What is the proper Head Stud extraction tool? - Now to reinstall them. Options

[stugray]

I have tried a couple of methods for removing the head studs from the case.
Double Nut rarely works.
I bought the NAPA stud removal tool, and while it is the perfect tool when you have room, it does not work in such tight areas as our middle head studs.

I looked for all kinds of "stud removal tools", but most of them are for broken studs, not for removing studs without 'munging up' the threads.

What does everyone else use?

A search does not turn up a simple 10mm stud extractor that wont tear up the threads.

If you don't believe this than go ahead and try it for yourself. Instead of making some smart ass comment.

rtalich - I still just want to understand.

I AM NOT exaggerating when I say that I have tapped thousands of holes in Steel, and aluminum. Some by hand, some with a dedicated tapping machine, and some with a tap chucked into a screw-gun. I have a 20 lb box of old used/broken taps to prove it....

If a hole was tapped with a 10mm tap, how is it possible to damage it by running a 10mm tap through it?

And I am fully familiar with the difference between starter taps & bottom taps. So just trying to learn here.
