If you exceed the temperature, your heat tabs will melt off, and more than likely, blow a head gasket, and possibility of cracking the cylinder head...

im not a mechanic, but if cylinder head overheats it expands and tightens against the pistons and seizes up

You blow the the head gasket and then your engine will go. You'll get exhaust gasses in the coolant and coolant will leak into the combustion chamber which is just...not good...at all. I hope you didn't do this...
