Don't cam chains stretch with mileage? Obviously there is no problem with them breaking, but cam timing would gradually retard with a stretched chain. I can't imagine why you wouldn't replace them if you're in there anyway.
Any idea what the lifespan of this hardware is? I guess there is "broken", where the guides/tensioners are so worn they make noise and beat things up, and then there is a judicious replacement interval where you're avoiding running them through the last sloppy 20% of their service life.
