You don't absolutely need rotating valves. If you have adjustable lifters you will find the holding devices helpful in getting them set. There are kits sold that include springs, guides, valves and all. I haven't done one lately, but I seem to recall there was a difference in the retainers or keepers between intake and exhaust. You may find it necessary to create a sturdy hooked pry bar to help depress the guides to install the clips.
