I looked up the link in source 1 of your chart. He said he measured those cams at .050" lift. I think in source 3 or 4 on your chart they measured YZ cams at .040" lift. I can't find the specs on 07 YZ cams. I think they say they are a little more top end oriented than the 06 but not as much as the 08-09. I'd like to install some YZ cams, maybe this winter, not sure what ones to go with.
