crazy question
 

please understand not trying to start a war but who has a c5 z06 without changing valve springs and how many miles. I am about to change mine thanks to the info on forum but wondering for what its worth how many have not changed and seen no issues and perhaps how hard their vette is driven and miles and years

wife and I bought a 02 with 107k and it was slow, (no power) about 110k we broke a valve spring and changed all of them along with trunions (non needle) now has great power !!!!! for what that's worth !!!!!

tks nobody else??

I've got a late production 2003 Z06 with stock valve springs and car has 91K on it. Mods are LT, off road x, Corsa extreme, Vararam, and tune. Mine will be replaced when i do a cam.

I replaced mine as soon as I bought the car. It had 51k on it...wasn't taking any chances. I drive my car on the rev limiter as part of habit...so...I was changing them...lol.
