I asked hassmaschine if I could send them to him for him to take a few measurements since he has an engine apart. So he said he would fit them to a head and see if they do in fact open the exhaust valves more.

They are a different part number from the N52/54 exhaust rollers but they might be a material change, or some other change that does nothing on our motors. Only one way to find out, fit them and measure.
