I’m getting ready to change my stock springs with Comp Cams 918’s. I was reading David Vizard’s book on cams and valvetrains and in it he talks about polishing the ends of the springs and rounding the spring tail ends. Is this a common practice?

Thanks

Check for burrs, I think you will find the way the ends are ground to get a consistent height they won't need any de-burring. I have seen this in his book as well.

PAC Racing Springs

High end Nascar type springs have the end completely deburred. It is very time comsuming and extreme care must be taken not to damage the spring. Any nick or burr unintentionally put on a spring cannot be removed without completing damaging the spring. For 95% of the racin applications this is not needed. A high quality spring from a reputable source will not need any additional work done to the spring.
