As far as I know SU needles normally had a 3-letter designation like AAE or ABL or something, so AN seems strange to me. I don't recall noting a jet number, never had to myself, but the needle numbers are usually stamped on the needle itself, as I recall on the shaft at the thick end, though maybe on the mounting flange. The springs were identified by a color, and as I recall there were three different stiffnesses. They were chosen for the airflow drawn by the engine, so unless you're swapping carbs from an engine of different size or one is busted you shouldn't have to bother with them. It's hard to say just what would be "okay for street use" without knowing more. But there is one person who can definitely help: Call Joe Curto. http://www.joecurto.com/ (718)762-SUSU (7878) He's the man.
