Below are my mods and current clutch setup is stock except for 14.5 mm rollers,47 degree helix, and green-pink-green primary spring. I need a starting point for 8000-10000 feet. Any help is appreciated.

Ok sounds like remove all rivets and add either 10.3 steel or 13.3 steel to outer hole.
I would like to hear from others to see if this is correct

Sounds about right. For stock sleds they recommend empty weights for that elevation. They run pretty good even if your short a few rpm. A lot better then bouncing off the rev limiter.
