The crossflow design is vastly superior to the stock counterflow design because gases have more momentum exiting the engine - they don't have to make a u-turn, so to speak before going out the exhaust port. That allows the combustion chamber to be filled faster. And yes, these ports obviously will be much better than stock if they can support over 150 naturally aspirated horsepower on a 1300cc engine.
