ramps of a cam lift curve are pretty meaningless, for they tell nothing about the velocity of the ramp as seen at the valve in a running engine. To reveal this in a computer analysis is a very complicated exercise, and geometry of the Commando valve train is necessary, which differs greatly to that of the Harley.
As Dances implies, a static design is one thing, but a dynamic evaluation and comparison is another matter entirely, and it would be of considerable interest if you would explain how this was done.
