The cam is in fact advertised as a "bolt-in".
Yes, it will "bolt-in" under the OEM spring, and no fear of any valve to valve interference. Very true, but not the entire story.
That said, the intake valve closing number is such, that increased compression is IN FACT needed, for that cam to expose the power.
10.25, 10.3 cr is the number, maybe a just tick more in a lighter bike/gearing.
I know this in my sleep, as we have worked with this line of cams in many, many, builds since 1996.
