Cam timing and ignition timing are two different animals. Cam timing has to do with when the valves open and close in relation to crankshaft position, or, more importantly, where the piston is in the cylinder. A change in cam timing will not affect your ignition curve, or the readings with a timing light.
To find out if a cam is advanced or retarded, you'll need to mount a degree wheel on the engine, find TDC, and rig up a dial indicator on a lifter or push rod. You can do it with the front cover on, but it's a lot easier with the engine out of the car.
