Ok i been digging and found several threads and now I have developed a theory for each number (yes baised on evidence):
E= exhaustI=Intake
5 = E2324 = I2403 = I232 or E248 (check gear pin)2 = I2401 = E248
I came up with these numbers baised on the fact that S14 gears 232 (orange) / 232 (green) and S13 240 (green) / 248 (orange). Then used your information, and the information from these threads:

Then used process of elimination with the colors, and type of cam (intake or echaust) then matched them to the numbers the people said they had. Lastly the only ones I didnt have evidence on was #3 intake, and #1 exhaust. But I figured there wasn't another intake left and I232 was missing so I placed that there. And since there was two I240s I figured there would also be two E248 thus being #1. So there is only 4 cams (I232, E232, I240, and E248) and 5 different numbers (6 if you count two number 3s). This is all based on information I have found. If you have anything else you can find please post it, or if you can confirm the numbers let us know.
