Guys who daily drive aggressive cam setups - Valve spring longevity?
Any hard data on this?
What kind of mileage are people seeing out of some decent beehive springs with close to .600 lift cams?
IS there a rough mileage estimate on when to replace a whole set of valvesprings? (i.e. every 50k miles?)

i was told 3years, 36,000 for pac/comp beehive. i see 50,000 out of duals and .600 lift. the closer you get to the max lift the sooner you need to change springs, just to be safe. My buddy has a cam that almost maxes his PRC extream duals(.670ish), and he said he will change them at ~20k.

There was a thread on Tech a while back . . .
both cars (LS motors) put about the same mileage on different cams over a year.
one had the revised 918s (cam under .600) and the other had the dual golds (cam over .600).
The 918s had lost more seat pressure vs the duals. Both drivers admitted that they both drove aggressively, stop and go traffic, and the occasional road trip.
I made a post just like this a while back on tech and on here . . . driving habits, duration/lift, bla bla . . . bla .bla . . . . lots of variables. Most of if not all of it is just hear say unless someone has the data to back it up.
