Spark Plug Replacement

I don't know if that was the official Chrysler stance or not. It my be just a recommendation by SSD based on his experience.

But I was wondering because the sealing area is a lot smaller than the bigger plugs if anyone had problems tearing up the bottom of the tubes?

I suspect this is the source and the reason is to get the tips out further. I seriously doubt Chrysler would have a stance since this is not the standard plug....... I would have the same concern as you, but I am supposed to keep the gaskets on my very early /6 head, due to a step in the plug seat area I think ....Pishta knows the answer on that one.
