Cam Question

[GenericWood@domain.elided]

I recently picked up a pair of 10548 cams for my '74 GTV.  Only problem is 
I'm not sure which is the intake and which the exhaust, or if there is a 
difference for that matter.  One has an "I" cast into it.  The other a 
backwards "N".  

My Giulietta cams are marked "A" (aspirzione/intake) and "S" 
(scarico/exhaust), but the "I" and "N" have me stumped. 

Any ideas?
