I'm a helicoil fan, too. A friend of mine uses something which, instead of looking like a tightly spaced spring, is more like a thin tube with threads inside and out. He prefers them. Principal is the same. For this use, recommend the Helicoil set with their tap unless you have a bottoming tap. Most general use tap sets won't suffice because they are tapered, not bottoming.

I'd use Permatex Aviation form-a-gasket/sealer #3 -- And only a very thin amount on the side of the mopar gasket that doesn't have the sealer on it already. This is what I've used for decades on cooling system flanged gaskets, including the JK water pump.
Silicone takes 24 hours to dry, and it's a bit too viscous for my taste on a flange like the water pump with low torque, in other words it may not squeeze out evenly. If you decide use silicone, it works as long as it's rated for antifreeze (see the package or mfg website) -- But take extra care with a small and even amount on the side of the gasket without the sealer already on it, and wait 24 hours before adding coolant.

Mr. T I looked for this and couldn't find any locally. I'd have to order it on amazon or similar but then i would have to wait a day or two for it to come in. Where do you get it from?

I would assume if there was a problem the pump would start leaking within a week.

Ok so something that came to mind. First, I have successfully tapped the hole. It was a little loose through the first couple of threads but gets much tighter at the end. I had 4 extra bolts so I cut one down so it simulates the thickness of the water pump and threaded it in the tapped hole and it held the 105in/lbs of torque. I think I'm good without the helicoil.
Second I think I'm going to just install and use the mopar gasket without any RTV type of any kind. The service manual says if it is the mopar gasket nothing is needed and I am still under the lifetime powertrain warranty and I don't want them to void it because I didn't follow procedure. Helicoils and RTV could potentially void this warranty especially at 163k.

Well it's complete. Didn't use RTV and followed the manual perfectly with torque specs ect....
It held the pressure test with my airlift so I added my coolant and all is well. No leaks.
Thank you to all who helped me out with this. Love this forum.
