Like I said in my first post, wikipedia is your
friend. Like I said before, Hulk has not only stopped the Juggernaut, but gone toe to toe with a character that wiped the floor with him in a single punch. That Wiki link even mentions the fact that he once held up a mountain. Take it from a long time X-Men reader; Juggs isn't on the same level as Hulk. He's just never been shown to have power even near that of the Hulk under any normal circumstances.
On another note however, he only wears the helmet to guard against psychic attacks. Even with it off, his head would be just as durable as the rest of him, but any telepath on the planet could take him out. Obviously not an issue in a fight with the Hulk though.
