Correct, but once the distributer is timed to the crank. You can turn your cams around 180 degrees or 47 degrees, 0r 147 degrees and nothing will change on your strobe light. The timing for #1 and #4 as measured by your strobe will always be the same. The both fire at the Z1 mark. There's no way one bank of cylinders ignition timing can drift in relation to the other unless there is something strange going on in your distributer cap. And none of it has anything to do with CAM timing. You can pull the CAMS out of the engine and the strobe will still go off at the same places on the Crank pulley.

Back to the original post, there is no doubt that having your cam timing off can cause one bank to run greatly different than the other, and light some headers up. There is NO way to determine this with a timing light though.

EDIT: I wish there was though!!
