Dont use 1.7 rockers with stock heads?

I cant see the rockers needing better springs. From what i understand the only time (besides if one goes) that you need to change springs is if you go with a more extreme cam. Because if you have an big bad cam you can start to get floating valves because the spring cant hold the lifter on the cam. But roller rockers alone should not need new springs.
