Although I'm not sure what effect it has on fuel economy.

Also on those delay valves, I just remembered my Dizzy doesn't have one on the line, so its safe to assume its unneeded. So I'm thinking the Distributor Delay Valve can be removed.
Oh yeah, forgot about that one too. The EFE hookup is there. Supposely closes off the right manifold till the truck warms up to keep fuel from pooling in the intake during cold running. That sounds like a problem waiting to happen. So just cap it off too?

Good to know on the delay valve. Never seen anything like that before so I wondered.
