The difference is like night & day. The first cam is very mild on the intake duration, but rather wide on the exhaust duration. This is commonly referred to as a "split duration", with a heavy bias towards the exhaust. The lift is also rather mild, a little short of the typical XE-R type lobe. Might make a good "stealthy" nitrous cam.
The second cam is rather large for a street car, but not outrageously big for a street/strip warrior. It would still sound VERY aggressive at idle, and could have some tuning & driveability issues. I doubt it would ever pass emissions, but nowadays, who knows. The lift is high enough to require double springs.

Thanks for the information.
The first cam comes with the Stage Four kit from WCC.
Now the second one comes from here: http://www.youtube.com/watch?v=_ANak8V7bo0
I was trying to understand the numbers (207/220) & (.571/.578). This will help me look at them and see the potential for horsepower with a set of heads. In medicine you get vital signs and such to tell you what is wrong with the patient. I’m trying to relate the numbers in the same fashion. What you see, should be what you have in a round about way.
Was wondering if I could go with a different cam with the heads and potentiaslly get over 500 horsepower with all the mods in the Stage 4 Kit.
Once Again Thank You

heads/cam
As with a post I saw in here sep of this one you had on heads, if you are doing a head/cam swap I would be very sure on the cam and heads. You need something between the ones you listed here one being mild and the other very radical and there are so many to look at. Just my 2c and advice.
224/228/581/588/114LSA cam, ET 215 heads, FAST 90 manifold, and tunning will net good operation and loads of power.
AFR 225 HEADS, 224 230 581 / 592 / 114LSA CAM another nice set up and can add the fast intake or not on either.

Both of the above cams will do about 460rwhp with the right tuning and a FAST, heads...ect.
The 232 cams do about 435rwhp cam only with a FAST.
If you are intent on running the optimum compression then milling and thinner gaskets will not allow a bigger cam than a 228/232 xer without notching pistons......example a 232/236 112LSA will not fit running the 11.6 static compression since the P/V clearance will not allow it.
Some heads such as trick flows and ETP's will allow bigger cams due to the different valve angles they have compared to the stock 15 degrees. Trick flow 215's have been used with a 236 xer without notching. Afr's will be limited as the stock heads are in this manner.

I have cam #2 and I love it. Double springs are required as mentioned. The idle is perfect. Car shakes at idle but not out of control. The cam screams after 3500rpm. See video below if you want.

According to their web page package includes these heads "AFR 205 cc Custom High Flow Heads". I was just going to bolt those heads up the my motor with nothing extra done to them. I going to ask WCC if I go with the #2 cam. Will this cam work with these heads??
Or should I just stick with Cam #1.
I was trying to get the V-8 Raped sound at idle.
What is this double spring thing? Is this a mod I need to make to the heads?
All this is very new to me

Single springs such as the popular Comp Cams "918's" will typically work for cams up to .600" lift. Above that, you need double springs. There are many on the market, some of which require machining the spring seats, and some of which do not. Either way, it's not a big deal. When you order the heads, just tell the vendor what cam you plan to use, and they will discuss the spring options they offer.
