I have just done the same job. If you look at the top of the holders they are numbered 1 to 10 by the bolts that hold them on. These are the fastening/releasing sequence. If you have removed all 10 of them, one also holds the guide at the cam chain end, 9 or 10, from each then they aren't fastened to anything.

I used a piece of wood as a drift and gave them a little tap in a few places all around them and they came free. They still took a little wiggling and pulling to get them fully free.

They are made to very tight tolerances and I think that the mating surfaces work a bit like suckers!

They are only fastened to 9 ft/lbs, next to nothing, so be careful fastening them back on. You will find one or two of the cam lobes against valves holding them up, so you follow the sequence of numbers on the top of them a little at a time to pulll them down.
