Evaluate Timing chain sets

That ^^^^ is the correct roller chain to use with a tensioner. The roller chains that have the "dog bone" style links are the chains that chew into the tensioner shoes. I have preached this on here for YEARS, but no one ever listens or acknowledges it.

Yeah, you know it, I know it, the majority here know it. Again, an example of a correct high quality roller chain and a beautiful MP chain tensioner after 8000+ miles, for a cam swap. Rollers rolling on the pads will burnish (for lack of proper term) and the links rub the pads imparting a scuffed appearance. After 8000 miles still not to that point as shown. Simply put, exceptional condition both performing as designed.
