The factory did not account for enthusiasts when they chose materials which is why it is common for high mileage factory valvesprings to crack or break when put through the abuse of racing. High RPM, increased compression, aggressive cam profiles, and other factors can cause valvesprings to perminantly bend out of shape (coil bind) or even break and drop into the engine (spring failure), potentially causing irrepairable damage.
