Hi

That looks like a pretty bad insert, it doesn't even have full thread coverage.

Options, if the hole in the head is not too large a heli coil or other type of insert could be fitted, failing that a new head or subi motor.

If you got it back in OK you now have some time to consider your options.

Hi

You would nee a special tool to fit them. Might be best to print off the photos you have and talk to VW specialist in your area, Wayne Penrose or Dunhams.

That looks like some sort of insert. Heli coil, recoil etc are a single piece of wire.
If it's be repaired once it's best to try and match that if you want to repair it.
Time-sert is a sleeve type, but not sure of other brands the same.

Each kit will have differences in the thread in the head, so not always easy to convert from one to the other!

Time-sert are expensive but worth the effort. http://www.timesert.com/

Other than that it's welding the head up and re-machining or simply get new/good used heads
