Question: What is the Best timing chain setup LA or Magnum

Just for accuracy's sake, the tensioners were never used on Magnum V8s, only on the V6s. It's my understanding that something about the odd firing pattern being hard on the chains and the tensioners kept them viable for a longer period at a time when Chrysler Corp. was beginning to offer 70 and 100K warranties...
I run them on engines I don't plan on digging into every couple of years.
I'm also interested in the current crop of timing chains, as my stash of old Cloyes Tru-Rollers has run out...
