Dual-Springs Kit?
http://www.vincihighperformance.com/superwebdeals.HTML these have been on the wife's since april of 04. when i put the vinci heads on her car this weekend, i will be using them again.
Patriot Dual Spring Kit includes Titanium retainers, Dual springs, Spring seats, and Valve seals. Good to .650 lift, direct bolt in, no machining required.
I went with this kit because I heard nothing but good about them and you just can't beat the price. I got them for $275 at ls1speed.com

Sounds like a good deal. Once I get my heads I will place an order.

Ok, first...figure out how much spring you need. It sounds like you are in the 140# on the seat, 350# of the nose range for a 6500 rpm motor.
Next you need to determine quality. Which varies. Crower actually lists the springs by quality. As does Isky and Manley. Others make you search. There is a reason some springs are $100/set and others are $300, or $500/set.
Then their is the supporting hardware. Most people seem to run the titanium retainers ($200-350) with steel keepers (Ti keepers are available for many retainers).
The penalty for losing a spring can be very high, especially with a single spring. Nobody is selling springs that are intentionally bad. And all springs will lose stiffness after a while (on a tweaked motor they are not install and forget).
I am curious who is building a spring, Ti retainer, keepers, and seal for under $300. I would have more than a few questions.
After that, Comp, Manley Nextek, Ferrea, PSI, Isky Tool Room and Endurance Plus (which I don't think makes a 1.290) are also good. Make sure the retainers match the dual spring pair. And the keepers match the retainers.
I would think that $500 is a more reasonable low end range for springs, Ti retainers, and keepers. Can the engine builders chime in?

I will be running the patriot setup on my 239 LSK Comp .651" intake lobe and 246 XE-R exhaust lobe and will let you guys know how it does. If it can control the LSK lobes, the XE-Rs will be a breeze.
