I think its safe to say no Speedmaster head will ever flow more and make more NA power than those E heads.
Unless someone wants to go through the time and expense of welding them up and re drilling pushrod holes. The Ti valves (can SM take 2.25 ") the epoxy, the max effort. Not happening.
Maybe I am wrong but I doubt we will ever see a Barton, Marcella or Gabby Speedmaster max effort head. I would trust their opinions on how much power, how good those heads are.
