Shorty C

Im looking to run some bigger cams on my b16a head, but the thing is, I need to replace one of the valves. I got them adjusted once, but there is still ticking noises so I figured they were burnt.

I was thinking of getting a set of ITR valves but was wondering if it is worth it to get the valve job done to my head to get them to fit. Its common sense that ITR valves will run better than b16 valves due to the lighter weight and better flow, but I was wondering if stock b16 valves were sufficient enough for skunk2 s2 or jun 3's, or even TOda b's, any of the bigger vtec cams.

Thanks
