The specs are at 1mm lift. That 1mm does not include rocker arm ratios whether they vary from one arm to the other or not. 1mm lift at the lash adjuster minus the rocker arm's radius is suppose to be 1.39mm minus the radius fudge on the valve. Why throw yet another variable in the mix? Getting an absolute rock solid check point lift is crucial you don't want your readings all over the map by numerous degrees. I am just warning that if you are not super anal about just checking a cam's timing, let alone changing a cam's timing, you are really lost anyway.
