As British citizen I do not have to apply for visa which is great but my past may get in a way ;(
You will have to give your fingerprints at US immigration. If these are already on record, you will have major problems. Your previous overstay will be documented.
If you are looking to simply visit the U.S. collect data that proves that you have strong ties with the U.K and that you will return. Be honest in all dealings with immigration, as if you are not and they find out - they will refuse to entertain you and simply disallow you from entering.
