i recently bought itr cams but am not sure if they are real..i know to tell id have to check the indicator rings..they are 98..they have 1 engraved ring and 2 protruding rings on the intake cam..so since they have these marks do they automatically mean they are itr cams?..the reason i ask if bc when i compare them to gsr cams..they seem to be very similar in size..you know how each lobe that sticks out comes in 3;s..the middle ones on each lobe are slightly bigger on the itr than the gsr's..other than that..its basically the same size..is there really suppose to be a huge diff in size or slightly in lobe size..thanks !
i know id have to measure but i dont have that measuring tool..
