Whats a good or decent price for the ITR and CTR cams..I am planning on adding the honda oem setup to my 1st gen b16 and I have read that either you should go with the CTR Intake Cam and the ITR exhaust cam..or is it the other way around..or does it matter? Can you use both ITR on both cams or CTR on both cams..or should you use the ITR/CTR combo?
