piper cam timing?

  1. #1
    hi all, the head i had built has my cams set at 110degrees which is correct , these are piper 285s. im having the head fitted at the moment all we need to do is put the cam belt on, i wanted to make sure about the timing. if the cams are set at the correct degrees should the timing stay the same or does this need to be set retarded for example?
    thankyou
