Question about the timing chains?

I've changed the timing chains and the guides and the tensioners on the 4.7 overhead cam V8 and I lined up the on the change it has the different color links I lined them up but after I rotated it to see when it you know I have a couple of turns by hand to see if it came back up to 12 and 6 and all that the little colored links were not in the right place do they move around as it turns or have I messed up somewhere.
