your comparing the 2.0 to the 2.2 head i dont think anyone has a definitive anwser as of just yet
Really that is kinda nice because if they were different it would more expensive for the 2.0 but not sure becuae you would think it would be more expensive but i guess not.wheelburns said:i had a part guy run numbers for me today and the 2.2 head and the 2.0 head are the same part number.
