Timing chain, dauntless V6

I know I will get plenty of different opinions on this question, but here it goes,
I was told that the timing chain should last the life of the engine and should not be changed unless you develop a leak in the cover. Is this true?

Not on the Dauntless. The factory gears are/were nylon on metal and prone to crumble. I'd be pretty surprised if original gears were still in a running engine 42 years after the last ones left the factory. It's not a terrible job to replace them, just get a service manual and follow directions.

I can not really see the gears, however, looking through the opening of the fuel pump I can feel that the chain has some slack. The engine is out on a stand so I wanted to change it but haven't done this before.
How hard is it?

It's not that difficult. Get a manual (Chilton or like) and go at it.
