You would have to get a degree wheel, and pull a valve cover where number one cylinder is. Set up a dial indicator so you could check the valve opening and closing. You need to first find true TDC, by using a piston stop by removing the number 1 plug, so you could mark the balancer for true O (TDC). Then go through the opening and closing of the intake valve a couple of times, or until you get a repeat of the degrees that match. Mark them numbers down. Then, do the same for the exhaust valve. When your all finished, you can then figure the duration, over lap, and the total lift, plus at what degrees it inituallystarts.
LOL I think your right Denny. I thought he was trying to Id the type of cam make?
