Even when using a plastic dart with a suction cup, the oil between the shim & bucket can raise the buckets. No harm done as long as you don't to drop something on a hard floor or down a hole that it doesn't belong.
I usually don't dis-engage the cam chain nor remove the cams completely from the head. The '96 & newer units probably will need to remove the steel chain guide.
With the bearing caps removed and the slot in the buckets turned towards the spark plug, one can tilt the RH end of cam up enough or roll the cam towards the spark plug and use a knife blade to dislodge the shim and then use a magnet to extract.
