I think what hurts the most the valvesprings is the lift...so close to .600 is not bad. Reliable setup; you could even run a single spring setup.

If you do everything like ur supposed to (oil changes, warming engine operating tempt, right oil) I would check them every 50K miles just for square and spring tension that's about it.
