Sounds pretty normal to me. For some reason, some nurses and doctors think all babies should be perfectly proprtioned or something is wrong, and that's just bogus. All babies are different. It sounds to me like you have a healthy, big boy. My DS was about that height and weight at 6 months. It sounds to me like she was trying to say that the % for height and weight aren't matching up, which they almost never do. Chunky babies are going to usually be higher in the % in weight than height and slimmer babies are going to be higher in the % in height than weight. There's nothing wrong with that and it's ridiculus that the nurse told you it something that needs checked out.
I would not worry at all about his head growth. 10% is not that big of a change. You also have to account for human error during measuring. Unless there was a big jump, like from the top of the % to the bottom, or vice versa, there's nothing to worry about.
