hi i bought these cams for my IX and the guy said it came out of his car and its 272s. problem is he doesn't know what brand it is and i cant find name stamped on it. there are some marking on it tho. can anybody help identify the brand?

 

I have the exact cames out of my car that I have as well that I have been trying to figure out what they are, from the research I've done I believe they are Brian Crower 272's, but I haven't confirmed yet.
