hello all, i'm in the process of getting some cams for my B16A2. I want to stick with OEM Honda cams. I was reading a few threads already in progress, I also read up on some stats and I have the following questions: -what are the differences between the 2 (i already know about the intake duration) ??? -what kind of gains do each offer on a relatively stock B16 motor with i/h/e ? -how would the increase in intake duration on the ITR cam affect my power curve and output? -i know these cams will work with a stock valvetrain but would it better to upgrade to CTR or ITR valvetrain? i welcome all inputs but make sure it's a valid comment that helps with my decision. Thank you all in advance for all your input and knowledge.
