All the motors with that technology will see gains with a cam change. I'm not sure if the M5's V10 has Valvetronic and Vanos, but they do have cams available for it. The S85 only has double Vanos. No Valvetronic.

Cool thanks.
So if Vanos just controls timing, there would certainly be gains with a high lift high duration cam.
No need for cam gears obviously, but a "big" cam sounds like a good upgrade.
*edit*
Do you happen to know what the lift, duration, and effective duration, of the stock cams are?
