   Yes, the pulleys rotates around the hub but I was under the impression that was just aid tightening the cambelt as there's no notches or markings to tell you how far you've gone. I know it will get the best out of them, but are they worth it?
   As for needing adjusting, I'm running piper 285's on std cam timing fine. After i rebuilt the cylinderhead I put it all back at std timing, if anything it feels more torquey

   Different cam profiles/how the mapping is done will result in the cam timing being adjusted.
   
   They dont have marks like aftermarket ones but still do the same job, hence why no one bothers getting aftermarket ones really
