ok ur prob confused out of your mind, well if you need new headset bearings, theres two ways to go about it. First way, you might as well upgrade to a bmx headset, which will prob be smoother, quieter and faster than your original headset ( but if you decided to do so, make sure that the size of it is 1 1/8). Secondly if you don't want to get a bmx headset, you might want to check the razor website to see if theres any replacement headsets for sale. If you have any more questions, look at the stickied threads near the top of the page.
