The reason you don't find anything in their "literature" is because they go into absolutely no detail. Why don't you call the company that comp worked with to design the cams, which would be FP, and find out for yourself.

For that, the Piper racing cams, with 12mm of lift (11 for HKS) will be the best. The duration is still 272 but your springs will keep up, especially if you use Piper springs (they recommend those with the cams) or some dual springs. Everyone has been using HKS 272's over here, but in the rest of the world they're getting the best results with Piper's profile for more low end and faster spool. Your idle depends really quite a bit on tuning and the idle can get really pretty smooth with careful tuning. No difference in idle, from what I've heard between HKS 272 and Piper. I don't think you want to go with 280's ... I think that's too long of duration and the reason most aren't going with that long of a duration. You might also be running into too much overlap with 280's but I don't know that, it's just my speculation as overlap was a concern with 272's and most people found it just barely wasn't a problem (from what I remember).

And by the way milki, I am running HKS 272's and have been happy so far. That is not to say that there may not be better out there, but they have been pretty good so far.
