Morph burm head size discrepancy?

Today, I received an email from someone asking for pics of my lab burm for comparison to his own lab burm. This is not someone I have any knowledge of, but I don't mind sending pics to people. However, here is a blurb from the email that has made me curious:

In particular, what I am looking for are pictures that show the size of the
snake's head compared to the rest of his body. It has been stated recently
that Burmese pythons of the "Labyrinth" type are prone to growing up to have
small heads compared to the size they would be in normal phase Burmese
pythons. Photos of other Labyrinth Burmese pythons would help me to
determine whether my python is growing up normally or not (he's about 11.5'
now).

I sent pics, and also stated that I've not seen any noticeable head size difference between my labs, norms, albinos, or green. Have any of you heard this, and is there any merit to it?

Don't have personal experience with the big dogs (or snakes, as it were), so don't know first hand, if that particular morph shows that as a "common" deficiency. Some snakes when massively power fed, to get them to breeding size fast, can have relatively small heads for their size. Don't know if that can occur with the big snakes.
