Some of the technicalities about head thickness, etc, I have problems explaining and normally I have to see the head or listen to it to "solve the problem." However, based in my experience what you might have is that your head might be too thin or needs break in...
Whether the inconsistancy in the thickness around the whole head has something to do I do not know. In my experience, thin heads tend to need break in to get a sound you like. (Break in is play it, leave it tuned, allow the head to tensed, etc, etc) What you are experience I had it with the major brands treated heads, example, LP heads). (Question here is your head a "see through" head???? In my experience the less see through the head is the more "broken" it is and more defined sound you get)
A thin head sometimes tend to have overtones when is not broken in. Another thing that is complicating your situation is a fiberglass conga (that has overtones all by themselves).
My recommendation here is to detuned your congas and start slowly to tune it, as even as possible, and see when do you get a sound you are comfortable with.
I know is hard when you buy something, and I do not know if you were involved in the process of selection, and not get what you wanted. You feel cheated. For heads, I follow my success in the past with sounds I like and is based in my observation of the head prior to installment and the sound I eventually get. Maybel you need to do that next time you invest in a head...
Other recommendations, experiences or comments might follow here.
