I'd say, the Land Of Waves Arc. Just look at all the ****ing blood splattered all around. The genjutsu in which Sakura is led to believe that Sasuke got ****ed pretty badly, that was pretty gory. Haku getting Raikiri'd, Zabuza getting his arm stabbed by Kakashi's kunais, him getting stabbed by countless swords, and finally, Zabuza ripping Gato's head off. Quite bloody.
Other arcs have blood too, but per 40-50 chapters of an arc, we get blood in like 1 chapter.
Exception is Obito's massacre of the Kirigakure nin. That was the most brutal thing in this manga.
