I agree looks like the Jesel Mohawk rockers, mounted to a single stand, each pair of rockers with there own shaft secured @ 3 Points, the center one a stud at the OE rocker shaft mounting points which secures the rocker stand, all of which I think is a one off setup some one had Jesel do for them. The thing about this setup is it requires rocker oiling thru the lifters & push rods, instead of the OE shaft oiling. This rocker setup is along the lines of T&D's Race setup, including the rocker oiling.
If I had the funds, I would rather go T&D's Steel Rocker setup, or I would even like to try Del West's Raptor Steel Rockers.
