Your new springs should have come with a spring height #. Also, aren't your valves multi-groove? If so, valves will still rotate.

If you have multi-groove valve locks, they don't grip the valve stem, you'll notice when you install them there is no gap at the lock sides, which leaves the valve stem free to rotate in the locks. Single groove locks & valves grip the valve stem and have a gap at the sides.
