You will also erode the coolant passages in the cylinder head from the corrosive exhaust gases entering the cooling system. And the water pump impeller will erode away as well. This is if you drive the car with a BHG for ANY length of time. If it gets really bad and coolant starts to enter the crankcase you will also ruin the rod bearings.
