It it not necessarily an issue, but I have seen a couple of broken pads on high-revving engines.

I fit the Tensioner with the Duplex Chains. Probably not necessary per se, but when you check how 'tight' they hold Cam Timing after the engine has a good few miles up, particularly at low engine speeds, it is 'tighter' with the Tensioner. This can be seen with an Ignition Timing Light (though there can be other reasons for scatter here).
Just be sure to knock the dimple on the cover out when using a Duplex Chain. It's at about the 4 O'clock position, if it has one.
