I agree with you 100% that they are two totally different things. If you want to get into "airflow into and out of the engine" what do you think cam timing does????

I will stand behind you as well in how cam timing works. What I think is the problem is a combination of the stock exhaust manifold and the physical cam lobes/timing. The header takes away the dip because it may get rid of back pressure causing a pressure wave or some magic unicorn theory. However if you changed the cams without a header it may do the same thing.
