I definitely wouldn't worry about it as long as they are eating though. You may try a larger rat once a week instead of two smaller ones depending on the age and size of the snake. I have started feeding my guy by dangling the rat by the tail slightly above his nose so that he will grab it in the right position for swallowing. I was having some trouble with him striking in the middle of its body and then getting confused and spending the next half an hour trying to reposition in a way that he could swallow it. This probably caused me more stress than it did him, but we have had fewer problems since I have found a way to get him to grab it by the head. These days he almost always eats normally and gets it down without incident.
A rat pump shows to have a very large head compared to the body at the beginning of life but that changes as it matures. The larger a rat gets the larger its body gets. Its head will never be larger than its rear once it matures. If it is you have a problem.

The XXL rats my Blood will take is several years old and still will occasionally eat the rat rear first.
