I was going to post some pictures of a kit like this after AI found one at work one day.

So is this the proper kit or improper kit?

Helicoil, as a trade name, has been around for a long time. If their kit is made up of solid, machined thread inserts similar to Timesert or Norm's, then there's no reason it shouldn't do the job.

The original Helicoil is, for want of a better description, a precision made threaded spring.

I think there are plenty of threaded holes in the engine that can be repaired with a conventional helicoil.

They are coils.
They are not solid

Right AJ, I know. What I am saying is that although the head bolt holes, and I think the main bearing holes, call for a solid insert, the balance of the holes can accept a helicoil type insert.

I think the kit I found said Head bolts on the outside of the container.
I will check at work today. I am back at Crest again.

Crest? As in Crest Cadillac in Milwaukee???

one in the same

That WAS initially the GM recommended repair, including for head bolts. It no longer is, as its longevity is uncertain and generally low.

why not just use something like a rivnut, i've used them for years in my line of work and i've never been able to pull them out of anything, aluminum steel NOTHING

and i'm talking about locomotive type forces... definitely more than you see in the head deck interface.
