Im in the process of replacing my headgaskets and got a full head seak kit from SOS and it came with valve stem seals. I got 24 of them but they are of different part numbers. All i could find was that half are seal A and the other half are seal B. Can anyone id which is intake and which is exhaust?

12211-PZ1-004 (seal B) has a darker spring
