Cam shaft Identification

I recently had the Heads, injectors and cam done in my 92 LX. I was told by the previous owner that the cam that was in the car was a B303. The cam is now out of the car and I have a friend who would like to have it if it is a B303. Is there a way I can tell by looking at the cam, like numbers stamped in it? I meant to ask the shop tuning the car to check this when it was on the dyno but I forgot. any help with this will be appreciated!

My F303 is stamped with that on it.
