Easiest way to measure the valve lift is with vernier calipers. Position the camshaft so the nose points downwards. Measure the diameter of the base circle (the top part thats actually round), subtract this number from the vertical length of the camshaft lobe (taking measurement from top of base circle to bottom of nose). Done.
Basically just take a horizontal measurement then a vertical. Then subtract the horizontal from the vertical.
Yes dial indicator does work too. This is just so much easier.
