cooling issues..., fine when driving, spikes when stopped. Options

So, got my conversion finally road worthy and have noticed that while I am driving around, the car stays at around 200 F. when i stop, or let it idle in my garage... the temp slowly climbs and doesnt stop (i shut it off around 230 F). I am assuming this is an issue with my fans.

I am running a front mounted radiator, using 2 push-style fans. A few things that i think may be wrong...

-There is no shroud around the fans... just the shroud that seals the radiator to the front (since they are push fans, they are mounted on the front side of the radiator, in between the radiator and the nose of the car)

- there is about a 1 1/2" gap between the fans and the radiator (this was just the way that ended up working for mounting the fans)

anyways, i am pretty sure that the cooling system is working (no kinked lines, thermostat working, fans do turn on) as indicated by driving and the temp staying cool, there is just something not working when i stop moving. let me know what you guys think.

well, new thermostat installed. no change... well, id say maybe a 5 degree difference while driving, now around town I am probably steady at around 195-200 moving a littler faster it drops to around 185-190. stopped, it goes to about 215. my local shop said that they can sniff for hyrdocarbons at the radiator and determine if there is exhaust leaking into the cooling system. I will be doing this on tuesday morning.

One other note:

I have been reading online and on other forums and it seems that normal engine operating temperatures are between 180-220. But most of you guys say that you are running between 150-160 while driving. just curious what some thoughts are on this.
