1G cam ID help

[92_6bolt_1290]

OK, so the other day I pulled my valve cover off to retorque my ARP head studs and I was looking at my cams ### they don't seem stock to me. They have no stock markings on them at all, but there is a #22 on the intake and a #20 on the exhaust I believe but it could be the other way around. At idle, around 900 to 1000 rpms I make around 15 inches of vacuum, no leaks and it pulled pretty hard through 7000 rpms the last time I tried it. I bought my head from someone in Washington and they didn't give me any info on the cams it came with and I would like to know. Any ideas, or do I just need to mic out my cams and try to come up with the profile from the lift?

If they are stock cams they will each be stamped with a letter I believe A,B,C maybe D I forget about D. But I came across the same question and I ended up having cam set A-intake(252)/C-exhaust(252) which are the two HIGHEST lift cams made for 4g63 engines and they are from a Hyundai.

The letter are stamped in a box. I know my regrinds have the 272's engraved in the side that faces the cam sprockets in-case thats where yours is.
