I have used these with a few cam only setups lately and they are holding up extremely well.

Thanks guys.
Reckless, how many miles do you have on yours and how often do you plan on changing them? Also, are you going to test them after you change them out?

My buddy and I put a set of those Crane dual springs on his truck. They're great pieces! AS for how long they can last, the valve springs today are made from super high-quality material, so unless you're pounding the hell out of them or using a serious supercharger, they should last at least 100,000 miles.

Great thing about those Crane springs is they have no damper to eat up the aluminum heads!

I have about 50 miles on them, 4 passes, and 11 dyno pulls

My car only sees action at the track any more. I occasionally drive it on the street.

Price varies, don't remember off the bat what my buddy paid for his. They don't require machining, you just drop them in and run!

No special machining, but you do have to change the valve stem seals when you install the new seats. We have the springs in stock right now, but the titanium retainers are on backorder from Crane for a couple of more weeks. (We have the steel retainers in stock, though.) They're listed on our web page here with the sale price that ends on Friday.
