Well, the crower 2's are a tried and true cam for our cars. I have taken the 2's up to 175whpish. With your set-up I don't think they will be that much of an idle problem. I ran them with my daily and a Jeep 60mm with no problem. Idle was a little rough but not bad. I think others can chime in on that. Also, as I recollect, the ramp speed on the crowers was not as sharp as the Cranes. The Neon boys seem to like the Cranes a lot more than the Crowers. I just get a little skeptical on the research behind the Cranes, in that, they use identical lift and duration numbers throughout (BTW where did you get those Crane numbers? Are you sure they are not Neon cam numbers?). I can't see why you would have the smaller exhaust valves using as much lift as the larger intake valves. As well as, the same duration. Even the stockers show a difference (and the man who designed our heads had an idea of what he what doing, lol) Its just a little thing, but it makes me wonder. As for springs, this is where I get mine; http://www.raceeng.com/p-7072-valve-springmitsu-4g63.aspx (ignore the 4g63, the springs work, but not the retainers etc.)
