I don't go by installed heghts,, I have a spring tester and I set them up with shims as needed so I have .060 to .080 from coil bind at full lift You will need to check your lift at the retainers after that to insure you don't have a roque rocker that has more ratio than it takes to coil bind your springs I write down each installed hieght with the shims and check all the valve lifts at the retainers I usually end up with less lift at the retainer than the cam should open the valves, deflection and bending of parts does that I have had rockers that make more lift than advertised as well as less lift
