If they do not heat The gear you will be REPLACING it and maybe?? along with other parts. Because if the gear walks off the end of the cam (and it surly will in short time) The cam will then start to walk In and Out of the block. Which in turn will mess up the lifters, Dist. gear, and so on as the small pieces make there way to the oil pan.
That is what happens when it is not heated. When the gear is pressed on with out heating it, IT shaves the in side of the gear making a Lose fit. And I have seen this happen to too many people and in some cases less then a weeks time.
also putting the cam in a freezer and Heating the gear. THE gear will all but fall onto the cam. It will press on that easy.
