I'm in agreement with Don - many of those parts just last forever and there's no need to replace them. I'm sure my Turbo has the original chain, sprockets, guides, tensioner, etc. at 213,000 hard miles.
What is the current state of your engine? If it's complete and intact, I would suggest doing a valve job and replacing the rings and bearings. Just replace the bearings/seals/impeller (or resurface the existing impeller) in the water pump, and if you want to go crazy put in a tensioner and timing chain. But, as Don says, you can just reload the existing tensioner and adjust the curved guide.
With those things you should have a good B-motor ready for another 100K miles or more. I am very comfortable with the B-motor ,so that's what I'd do.
The main point is, if the motor has a good water pump shaft and jackshaft in it, keep those two happy parts together - the main time people run into trouble is trying to combine a used jackshaft with a new pump shaft or two used parts from different engines.
