Face plating and pro shifting remove the little engagement teeth on the synchros and replace them with a fewer number of much larger teeth. It just makes it easier to get into the next gear quickly, but it can make it extremely challenging to downshift and drive on the street.
Those types of trannies are referred to as "crash boxes".
