I run dual Edelbrock 500 carbs on a FM 257 intake using Trans Dapt adapter plates in my 56 Customline.

Yep.  Aluminum is much easier to work with than iron

There is an FM255 intake on EBay right now for $150..  It's rough and one of the mounting ears is broken off. Can this be fixed?

Having a PCV valve while using the Edelbrock 255 intake is not a problem.  It’s just a matter of using a road draft tube valley cover (same at Thunderbird or later model car/pickup) and using a PCV valve grommet in the rear breather hole of that cover.  The ¼-20 threaded hollow stud does need to be cut down so it’s not preventing the PCV valve from seating securely in the grommet.  While the center vacuum port on the 255 manifold is a potential vacuum source for the PCV valve, either carburetor having a 3/8” vacuum port would also suffice.  Another option is to either drill and thread the back of the manifold for a PCV valve vacuum source or add a vacuum port to one of the carb spacer/adapters.

I assume you could install a PVC with an FM255 intake?  In Ted's photos above, it looks like there isn't room.

That's a good question. Maybe Ted has the setup there?

Also, I do not see a vacuum advance unit on the DIST -

No real reason for the road draft tube.  My car was stock when I bought it.  When I rebuilt the engine I retained the road draft tube.  I plan to change it to PVC.  Haven't got around to it yet.

Here’s a Y with the Edelbrock ‘255’ dual quad manifold set up with the inline Holley model 4160 carbs.

I assume this means I won't be able to use my road draft tube and will need breathers in my valve covers? 

Yeah. why the road draft tube? Is it for looks?

To use breather caps on the FYB rocker covers is sacrilegious ...

I have read different reports. The H4000 and/or WCFB will not interfere with the 57/ Dual Advance Distributor. The 4160 I am not sure of. Someone either here or on HAMB must have done it at some point.

EDEL put that pad more rearward for a reason (better flow). I bet EDEL was knowledgeable of what was coming later and had he stayed with FORD (MERC), things may have been different (IMO)
