Thanks for posting this info. I had the for sale thread up, wish I would have seen this before I boxed up and shipped them. I'm guessing those R2/R5 markings were on the other side of the shaft from the "IN/EX" markings that were in my photos. I didn't know to look for those, or would have definitely taken a photo.Steve shared a link that helps to identify true 06-08 TSX cams. Might as well share it with everyone here:

Thanks for the info. Seems like the ones for sale sold were either missing the "R2/R5" markings, or the guy just didn't take pictures of them. Either way, they're sold.
Hopefully the buyer takes a look when they arrive and confirms. I got the cams from a reputable seller myself, and had no reason to suspect they were not TSX cams. And I personally would never sell something dishonestly. If the buyer is reading this thread, hopefully they take a look once they receive them; if there is anything suspect, please contact me so we can get it resolved. I don't suspect anything amiss, but now that we have a way to confirm for sure the camshaft I wish I could have done it before shipping.
