Timing chain set

I will say, when I bought my ramcharger eith 104,000 miles, I replaced the timing chain with one of the cheaper cloyes roller chain and put a tensioner on it as well. I had to change the timing cover some 8 months later and the tensioner was all chewed up from the roller links. Maybe 8,000 miles. I took it off. Now, I still use a tensioner but I make sure the back of the chain is flat where it rides against the plastic rubbing block.
