SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

since someone mentioned Whiplash cams.. i am curious if anyone has ever seen one on a dyno or at the track? I have seen a lot of videos about how amazing they sound but not how they run..
I hear they perform not too bad especially on low cr engines, there's no dyno or track shootout I know of, never used one so can't say 100% but I've never hear any complaints from anyone running one.
Not much of an answer :)
