Chris:
If the price is right, they will come. There are a few 'better than 906/RSR' rockers out there but nothing less than $3k. Hell, the 906 rockers I bought are all needing reground and rechroming at $42 each plus 15% hazmat fee. Hexavalent chromium anyone?
As for friction, your analysis agrees with what ive been told and other than really hard materials, oiling can provide a significant improvement, hence the decent life of the chromed feet being porous and holding oil (as well as hard). Given the aliphatic nature of a carbonaceous surface, I should think DLC would be excellent for holding a film. I've often wondered if coating the inside of the pistons would see a significant temp drop due to better wetting of the metal.
Please post as you progress.
