My friend picked up a set of cams but they dont have the usual H01 engraving on them. They came in the correct boxes but who knows. There are a couple of cast markings in between the lobes. The intake side says 'M' and '2' while the exhaust side just says 'M'. Can anyone confirm what these are? If you need me to post pics, let me know exactly what you need and i'll get em from my friend. Thanks

I can get measurements too if needed. My assumption is they are S2S2 according to one other post in the archives.

 

Ive confirmed they are skunk2 cams. But doing some research, both stage 1 and 2 cams have the same castings. M and 2 on the intake side and M on the exhaust. Please help.
