I have spare heads that I will probably no use in the following years and I would like to know if it is better to remove the camshaft or at least the rollers to avoid damage to the springs.
thanks

Not sure, but I will note that I once bought a used cylinder head (6g74) (stored at the junkyard off the car in a covered building for an unknown amount of time) that I had to use a fair amount of effort to get the valves out of the head... Since I was porting the head this wasn't a big deal, but I doubt it would have worked just bolting it to an engine..
I would recommend that you bag the head to limit problems...
If it is going to be stored for an extended period, it would make sense to at least remove the followers so none of the valve springs stay compressed.
I would bag it after spraying down with some kind of light oil, and keep it in a dry place.

I concur,
Best to remove camshaft. Even better to remove valves if you can, so you can apply some grease/oil to seats and guides. I've bought NOS heads in the past and seats, valve tips, and guides had flash rust on them. If you have the ability to keep these in a stable ambient temperature environment, they should store for long periods of time. Yes springs can be damaged if allowed to sit forever, but our stock springs are so wimpy I wouldn't worry about that aspect. More likely that some insect or critter could take up residency in a port that has a open valve. Yes bag and tag it like Wayne says.
OK, great thanks
for storage you want a spray that is more tacky / sticky than runny like oil so it stays on the part , not the shelf
think of the fresh machined parts wraped in the oiled paper that are always sticky with a fine grease like coating
it may need washed off before you use it but that part will wash up nice and clean when you do
Should I note the position of the followers and lifters to put in the same place, or it is not necessary ?

Thanks
I heard about this for slider followers but not for rollers.
