Terry,
Interesting stuff. But one question. You state:  
Because these engines are so restricted by the valve & seat, then 
the only way to improve them is by having very fast lifting cams and
therebye
having the vale open for the longest possible duration. The rocker
arrangement has little to do with this.
Doesn't the increased rocker ratio cause the valve to move faster as well
as further?
Or is it just a case of to little a change to make a measurable
difference.
Thanks,
Bill
