Help me identify these cams

[node]

Im putting my low compression turbo motor togeather and I have a few different cams sitting here that I got with my motors.

I have three different kinds of KA24DE cams sitting here. They are marked 1, 2, and, 3. I think the cam marked 3 is a 95+ intake cam correct. The cam marked 2 is perhaps a 91 intake cam and maybe the one marked 1 is a 91 exaust cam? Uhhh why cant nissan just label everything like toyota does.

Im just guessin here. if anyone has the valve cover off please let me know what goes where.

ThanksJim
