I believe you are referring to the SchnellKampfGeschwaders and Hitler's "Terror bombing" of England by them. They were most certainly FW-190G's as these were the planes specifically designed to be long-range fast attack bombers.
That is why the RAF tested so many FW-190G's in their Enemy Test Flight.
In the very beginning they were FW-190A jabo-einsatz's but these were quickly supplanted by the FW-190G series.
