Is there an limit on stock valve springs? Would you install valvesprings with 130k miles in an dohc zc with regrind cams?

I've been told that our springs are pretty stout and will last a long while. Plus, I was told that in certain setups, people run the OE springs in higher rev applications. Upwards of 8200+... But since you have, what a stage 2 cam? It just might be better to upgrade...

They certainly can get softer. It's metal fatigue. As far as OEM springs with 130K on them, I wouldn't worry at all.
