You want a rowdy idle, or a streetable one? If you were going for low 12's on a stock blower car, I'd go VS with 1.7 rockers. If you were going for 11's, and don't mind flipping the bill for a better power adder, get the XPZ. Contrary to poular belief, a milder cam with high lift rockers will give you more pwer than a very aggressive cam. Personally, I'd get the VS. Run it through the point you have more supporting mods, then put on 1.7 ratio rockers and dial it in.
I've had some private discussions with people in the know about the Intense cams, and for now at least the ZZP ones are the best out there. Either the stage2 or 3 will make more power than stock, but aren't all that well performance balanced. I know Mike K. is looking to do a couple of custom grinds for his store, but don't know a date yet. There will be an all out grind, a mid level, and a general performance.
As far as the TEP cam goes, it's an all out race grind, and shouldn't be used without the proper headwork. It looks like a decent cam, but a little "old school" technology compared to the Comp cams stuff.
I'd check out the HP cam chart on Club GP it really will tell you what's working.
