Another Eddy head question....
I am amused that people purchase an item from a manufacturer and then ask everybody but them about what things work with them. I would think that the people who make the head would be best qualified to answer your question. They have spent thousands of dollars and lots of parts when designing an item like a cylinder head. You trusted them to buy their product. Try to trust them with their advice since they have skin in the game so to speak and the others don't. IMO
