If you read this Hughes who sells these tensioners does not recommend their use with a roller chain. And a cordial chain will not provide the strength for higher spring loads for bigger cam installs. The chain to sprocket engagement using a tensioner with a roller cause linear variations of the speed of the chain and will effect operation.

This is one article from a seller of the chain. The first pic is the correct chain to be used with lighter strength valve springs and tensioner. These timing tensioners should not be used with a roller chain due to linear variations and the cam jerking around with a roller chain use.

But you need a stronger true roller chain for High performance cams. Those are words from Hughes. A cam jerking around could cause premature wear on everything. Who's to say maybe even the lobes and lifters? Words from many seam to warn against the use of a tensioner on performance SB mopar engines
