No you don't have to change the springs, it is only generally once you exceed a certain RPM where the valves will want to float that spring changes are needed, usually if you take the RPM above approximatly 5500 RPM that it is suggested. If they are worn out it is also a good idea to change them.

If you use the 1.6:1 roller rockers you have to use adjustable rocker studs and machine your valve guides so the "valleys" are deeper.
