Cams 98F3

Anybody out there know what the markings mean on the intake and exhaust cams? I have several pairs of cams, and they have differant color ink dab marks on each set. (white, blue, green and yellow?) they also have markings which are letters and numbers. Measuring them with a digital cailiper shows a slight differance on the two sets. Currently my bike has the cam with the largest lobes (orange or yellow)
Thanks for any info.

cam, duration, degree

Ok. no luck with the markings by response. So heres another question: has anyone else ever done a cam swap, and what valve clerances did they use. The Honda 600 engines use a shim under the bucket that can be replaced with a diff size. When I built my engine, I went to the tightest tolorance that the haynes said. Heard somewhere that all the oil/bearing/cam tolarances were suppose to be tight, other than the crank? Anyone else heard of that? The motor I built runs real strong, it's that I want to adjust/check valve clearances before spring and need some info.
