So I'll put the spark plug in to the insert (with the 266) and then try and thread it in the head with the new insert? And if I fail at that I move on to the big-sert? You guys are great by the way, thanks for the help, appreciate it.
It looks like the helicoil insert broke while you were removing the old plug, maybe? you may have the lower half stuck and spinning in the hole, or worse, spinning itself further and further into the head as you tried to put the new plug in. It may be sitting low enough to contact the piston at TDC or fall into the cylinder. normally if you pulled the helicoil completely out, there would be nothing for the new plug to thread into at all. Check and see before you continue.
important point - if there is still part of the insert in the head that needs to be removed
you can get a very inexpensive bore camera to check out the hole and cylinder (i bought one for $12 works well enough)
I'm thinking/hoping BareBonesXL is right; I don't have a better picture than that to share but agree it doesn't appear broken. I had it in my hand but didn't inspect it enough for breakage, just going off the picture as well. Having said that I will be sure to inspect it with a bore camera; good excuse for another toy

Yea, I'm going after that camera he linked to in the video, a good one for the price.
Whatever you end up doing, be aware that red loctite, AKA 266, is generally considered to be permanent.
It permanent to 4 or 500* which is what you want as it will never see half that temperature at the threads. The engine would fry first before that breaks down. Liquefies at 600* which is how you break it down when ever possible. Like say when used on drive shaft bolts.....for instance.
... I believe the guy in this video uses correct red loc-tite and he taps all the way thru the head then uses an insert which is as long as the threads on the plug. MOST IMPORTANTLY he 'swages' the top of the insert so it does not come out next time the plug is removed. Watch the video all the way through to see what I mean. He uses a great kit and I am not sure what it's cost is but well worth the investment vs taking to a stealership and having them screw it up and end up charging a bundle.
