289 or 302 valve stem seals on SBC head???

How's everyone doing been awhile since I've been on here, I have a question I can't seem to remember, I have a 89 chevy with a 350 it needs valve stem seals, now I've done this before hope some of you have too. I want to use SBF valve stem seals but I lost the part number for the ones I need and can't remember if I used 289 or 302 seals. If anyone can help me out with the p/n for the ford seals I need for my chevy I would really appreciate it.

Thanks cole
