I have two sets of Miller Rocker arms and his shaft rocker set up. I have never had a problem with them and one set came from Paul Kane several years ago. They have the Miller trunnions. As I recall Paul was affiliated with High Flow Dynamics. But I could be wrong. If you click on the link for HFD and go to specials you will see Miller SBF Rocker Arms for sale If you look at the description they clearly note that the trunnions are not Miller.
Apparently Something Changed and Jim Miller is not able to stop it. They don't indicate that they are Xdistributors quite the contrary.
