Replacing timing chain
I've used slingers with double roller timing chains for I don't even know how many years. Never had a problem. And if I remember correctly, 340's were factory equipped with double roller timing chains and a slinger.
As for the modern tensioner, I have one, but didn't have the nerve to try it, as I wasn't convinced it would be safe with a double roller chain. I did pull the timing cover as I was finishing up my 65 Barracuda header install, just to check the timing chain, as it's been in the car for probably a dozen years or more by now. On the other hand, it's not my daily driver anymore, and probably doesn't have 10,000 miles on it. Anyway, it was fine, so I didn't put in the new double row chain I have in the box on a shelf in my garage. Will save it for my 67 Barracuda, if it needs it.
