what happened to the guys that stripped their threads? The hole is pretty hard to get to and I would imagine that the only way to rethread them is to take the block apart...

This is what I remember from some posts on this forum during the early days of the European recall. As we know, these oiljets are responsible for not only lubricating but for cooling the underside of each cylinder. In a couple of reported cases, the dealer tech did not center the alignment pin of one or more oiljets when the bolt was threaded in. This allowed for insufficient pressure to push the oil through the jet nozzle since the oil was just puking out between the oiljet base and bottom of the engine block (the oiljet base was not flush with the block). This resulted in poor (or no) cooling and lubrication on that (those) cylinder(s). I don't recall the exact damage done but it involved replacing the owners' engines.
In the case where the bolt was cross threaded (DIY), the owner used some sort of metal adhesive to re-install the bolt. As far as I'm aware, so far, this has been working OK. The threads are a very fine pitch - difficult to clean and difficult to re-tap. I'm not sure a helicoil would work here.
When I did mine, I noticed that it was particularly difficult to thread the bolt in the first cylinder. The threads on the engine are very delicate and require extra attention.....

Access to the #1 jet bolt is impeded by the presence of the oil pump hardware. Also, the threads are not positioned straight "up and down" as the engine block itself is at an angle. One needs a flex extension of some sort so that the "slightly off angle" can be achieved.
Certainly if this install is bungled, Bad Things can happen, so some caveats are justified... But as Prolene mentions in my install thread, this job is really Mechanics 101. (OK, maybe the final exam in Mechanics 101. ) If you take your time, use the proper tools, maybe invite a buddy over, I think you should have every expectation of things going smoothly.
I just had my bolts upgraded last week during the vortech install. The one in cylinder three was loose. Would have hated to see that work it's way out. I was just wondering if anyone else had the same experience.
