I thought I might stir the pot with this old collection of useful information. I did use the Kenny Harmon F cam on a cruisin image 836 ported by me. I plan to move the KH F cam and its cam towers to another head and put a Honda F2 cam and its towers back on the 836.
For a 997 build I'm comparing the 125-75, Engle BR21J, and the Kenny Harmon F. I have an RC 315 but it has an oversize base circle on the #1 intake, it hits the cam tower. Same lift, who knows what that did to duration.
