When you changed the head gasket did you send the head to a machine shop to have it checked and serviced?
There's no such thing as "ice crystals". That is excessive corrosion do to lack of proper servicing. I suspect that you didn't perform the things needed to prevent overheating.

Is there an excess amount of water coming out of your exhaust?Did you flush the radiator? Also an over heating problem could make the water pump go bad also.
