i was wondering what the stamp is on an ITR head, i was told it was PR3, but im not too sure...also..what are the stock cam sprockets stamp...pr3 as well?..i know the b16 and ITR heads are quite similar.....and how can you tell ITR cams from the rest?

 

c5 heads are coded PR3, i would think that the sprocks would be stamped similarly if at all. The most accurate method of discerning R cams from other B cams is to measure the lobes. i.e Lift and Duration.

EDIT: For future reference the ITR specific forum is located @

They can probably get you the exact specs on the bumpsticks.
