That's not necessary for a hydraulic cam, unless you have lash in the system or you can't keep the lifters pumped up.

Its called a Rev Kit....it is a set of springs that works under the head and pushes on the top of the lifter. This keeps the lifter in constant contact with the cam ...even in the solid lifter application. As said above that takes the complete lifter weight out of the equation.
