Is supply catching up to demand yet?

Have you ever compared the shape of a Speedmaster valve to the Ferrea that you wanted? Not thinking about running one. Just wondering if they copy the Ferrea profile close enough that a Chevy length 2.08 could be used for single valve head tests like you are doing.

Any Edelbrock head I go with a 2.08 valve I consider a race head and at that point I wouldn’t put a speedmaster valve in it so I wouldn’t even bother testing that. I do run Edelbrock exhaust valves in my 2.08 heads but only because they are smaller and lighter than intake valves. And I fact I’ve never hurt one of their exhaust valves. That’s kinda why I’m curious about the Ferrea exhaust valve.
