Differences in cams?

[HR radness]

Does anyone know how to tell stock subaru camshafts apart?  I have some left over from a build and i dont know if they are wrx, sti or what.  Never used them and they came loose.  They all have stamped markings but I cant find a chart that has the different cams listed and for what motor

This sounds interesting. I've got a set of ej25 cams on my bench if you want me to take a few pics to compare.

Do they not have AVCS holes? If so then they are for sure 02-05 WRX cams.
