The stock valves tend to break.
2. Have these been tested in a dale yet?
No, the springs have, but not valves
3. What is the cost diff between these and stock valves?
about $75
4. If these are new and have not been tested what type of warranty is there if a valve dies after install.
I always offer a warranty, they will be running in my engine very soon, but kibblewhite's reputation speaks for itself. They did do some valves for cannondale when they were in business, with great results, but they went bankrupt and stuck kibblewhite. I have have a hard time convincing them to build these.
5. Also if there is any type of warranty, can anyone install without voiding a warranty?
They must be installed by haydug cycles or timbomoose to qualify for a warranty.
