will this hurt anything? (crack)

Eh.... I'm guessing it's a lower intake on the head side right?

I wouldn't worry about it. Maybe put some JB weld on it.
People have ran their cars with bigger cracks in it then that, so why not?

You may have water seepage through the crack. Press silicone sealer into the crack real good and use the sealer on the gasket side too.
