They would need a map to get the most from them goes without saying. I have always used the Tomei cams found the Poncam range really progressive power band giving you extra drive from low down all the way to the top, rather than mid range kick.
With the Nismo springs in place you would also be able to up the rev limit a touch without the worry of valve bounce high up. By the way the Nismo springs are made and developed by Tomei as the two companies are very close. I spent a day at Tomei and Nismo headquarters back in 2008.
I ran Tomei cams in my road car for 5 years as my everyday motor for 100,000 miles touching the rev limit daily
P.S. It was in a Nissan but not a Zed!
