When you sparred with headbutts, did you get anywhere? It seems to me that you rarely get enough distance to be effective and anyone who knows you can headbutt will defend. The guard from BJJ would hold you so that your headbutt would never gain enough force and not be to your soft face area anyway (your breastbone is hard). As I remember (could be wrong), Gracie BJJ did include head butting to off balance the opponent, as well as elbow strikes to the necK).
I seem to remember that Pride had an early fight where someone trying to throw a headbutt had their neck twisted and he cracked his spine, but I could be mistaken (I have always felt that Pride seemed determined to make sure there was blood and talk of broken bones to bring out their target audience).
