That would be uncommon. There have been a number of photos of soft, wornout cams both here and on the other Norton site. All of those had lost a lot of lift.I've seen a drive side lobe on a 70 that had pitted hardening face marks on the ramps yet the highest point had no marks at all.
If one absolutely must peer at every moving part, then there are cases to part, main bearings to check, conrods and Conrod shells to inspect and so on.
I wonder if some of these non-runner bikes are ones that came apart for inspection and never quite went back together again....
