I just did the write up for the green Team Stripe shirt where I kind of questioned the logic of Hulk, Spiderman, and Iron Man on the same shirt and then I find the same characters on yet another (granted, very cool) shirt.  This is what happens when you write orders late at night.  Still not sure of the logic here.

I seem to recall Iron Man fighting Hulk at some point a long time ago, but I can't find anything relevant.  Nothing like looking at speculation regarding rumors that are supposed to come to fruition in 2008.  Lot of worthless info out there.  I think the Internet is due for an enema.  

I did find some debates as to who would win between Hulk and Iron Man, but I think it painfully clear that unless Iron Man can blow up a planet with his repulser Hulk would clean his clock.  You can't hurt him and he gets stronger as he gets angrier.  Sure, Iron Man can fly around, but I've seen Hulk tear up railroad rails and throw them like spears to shoot down jet fighters.  Eventually he would get a hold of Iron Man and pull Tony Start out of his breathing pipe.
