Question

Valve Spring Life?

What's the typical life of a dual valve spring from say Comp with a .600+ lift cam in a motor? 15K miles or what?

Most people check them about 20K and many are still fine.

Thats just what I have read on there though milage may vary.

Depends on the seat pressure. Typically the lower seat pressure, the longer they last. Hyd. roller camshafts don't require a ton of seat pressure, therfore they should last quite sometime.

Also depends on what lobes the cam is on. The more aggressive lobes tend to ware more on the springs.

I have no idea about the lobes on this cam. Its a FMS grind so I'm assuming it's pretty aggressive.
