Just kidding. The single beehive spring is much lighter and performed better on our Optron valvetrain dynamics test cell. Lighter valvetrain = greater durability.

Yea, I have them in stock. They have been on several engines on the dyno, one of which was our Camaro engine - 8 hours of durability. They have also been on the Optron.
