The head is identical on B16B and B18CR, cams etc are all the same dude.
no. The cams on the EK9 and at least the 2001 USDM ITRs have 3 degrees longer duration.
The difference is slight but it's worth noting. But with that said, don't expect 5whp across the entire rev range from such a small change. Cam gears on the "regular R cams" would likely unlock more power.
