ok i just purchased a set of 98 itr cams the thing is that when i compered them to my gsr cams they looked almost identical is there a real small difference between the itrs and the gsr cams as in lob hight?????

 

Yes, there is a big differece but nothing that you can just compare and see with your eyes. If you really want to measure it, you will need an outside micrometer to measure the actual lift. But to tell the difference visually there are rings on the dizzy side of the intake cam. Well here is the link:
