If it was exposed to UV and other stuff, for sure age would be a determining factor. But since it is protected from the environment,... well, hell, I don't know. Think you could extend the life span some

Mine has 125K on it and it's doing fine. I just wouldn't race it or do anything drastic.

I would say do it for peace of mind and the fact the the 3.5L is a no tolerance motor and can bend valves if it breaks, right? 100k is 6.5 years at 15k a year so it is due by a timeline. Heat and time are contributing factors. Like the others stated, check for cracks and the ribs for dry rot. I think I read in past post to do the water pump and tensioner at the same time while you r in there.
