Putting together a B20 vtec and was curious how you know or can recognize if what you are purchasing is indeed from an ITR?? Looking at buying some cams which I do know how to tell if they are ITR but if I wanted to purchase springs and retainers from an ITR head how can I make sure they are legit?? Thanks for any and all help. Happy Thanksgiving!!

 

They should some paint on the springs... The intake springs are yellow while the exhaust should be blue... If you want more detail, i can give the spring heights too... Hope this helps..
