If it is going to be a while before you use them, and you are going to go through them anyway at that time, I would just spray some WD40 on them and sit them on the shelf. Plastic bags tend to make a lot of condensation when the temperature changes, I dont like using them. If the heads have been run, they are probably pretty oily anyway, they should be fine. if you can store them in a heated area of the house instead of an unheated garage, it is even better.
Hope this helps,
