I know I saw this thread somewhere on here, but can't find it anymore...yes I did a search. I want to know the VISUAL difference between the GSR and the ITR and/or CTR cams. I know that the ITR/CTR cams are more aggressive, but if you were holding them in your hands, how could you tell the difference between them all? Is this possible? Thanx fellas

 

the lobes will be bigger on the intake cam on the ITR over GSR
same for exhaust but u have look closely on those.
of course u need both cams side by side to tell the diff.
