    Would lightened valves help avoid failure or is it just prolonging the inevitable if you're spinning over 9k?

    willing to bet will be VERY SIMILAR to this

    As I recall, non hydraulic rockers (with a specific cam) were available awhile back but were costly.

    Here's some add'l info

    100% billet from 2024-T3 material (with full certification) and 8620 steel sub assembly components.

    Hopefully have a prototype in my possession in the near future......
