Specs on both:

ITR:

Intake: 240 degrees duration, 11.5 mm of lift

Exhaust: 235 degrees duration, 10.5 mm of lift

25 degrees of overlap


The CTR specs are pretty much identical but the intake cam has 243 degrees of duration and 28 degrees of overlap. The difference is negligible, like I said. I just went with CTRs because that was what was available to me for cheap.
