For what it's worth, and to offer a different opinion, my thesis advisor told me that admissions committees don't have the time to care about a minimal overage like that, and it's more important to make sure that your SOP and writing sample are your best possible work. By all means, if you can cut the SOP down and it is better, do that, but I am under the impression that our applications will be judged by their actual content, as opposed to precise adherence to word count guidelines. It might be a more productive use of your time to get more opinions on the SOP from people in the field than to try and cut 30 words.
I am, of course, just an MA student and not a faculty member, so take that with a grain of salt.
