Use a dial indicator on a pushrod (dont use on a rocker as the spring could 'deform' the lift due to hydraulic lifter preload). Your lift will be pretty close to dead nuts by using a 1.5:1 ratio and then you can determine the duration by TDC and lift @ .050 per a cams spec. Use a intake and exhaust to see if its a split duration cam.
