Other than directly measuring the lift and duration, is there any EASY way to distinguish different sets of OEM B series VTEC cams.......GSR vs. CTR vs. ITR vs. B16A??? Are there specific markings?

I'm sure it is very easy for scammers to sell VTEC cams represented as ITR or CTR, but end up being GSR or B16A.
