Many of those dual-roller chains will gain slack as the roller axles wear in. The double rollers give up a bit of accuracy to gain adjustability and strength for pulling big cams against stiff springs.

I always degree a cam when I install it. I start dot-to-dot, and install it with the cam gear dot at the 6 oclock position and crank gear dot at 12" to make it easier to eyeball the dots really are lined up.

Ok thanks. I’ve never degreed a cam before. I’ve been watching some YouTube videos. With regards to a kit, I see that Jegs and Summit sell one for about $90 and the Comp-Cams one is almost $180! Why the huge difference? Can I get by with the less expensive kit?
