Is there any benefit to having ram tubes or velocity stacks on say, a conventional style fixed venturi carb on a plenum style manifold?

When you say velocity stack, do you just mean a bell-mouthed opening? Try the Best Bell article for an in-depth look at things. The short answer is yes however.

My query is essentially , If done properly what sort of gains can be expected?

More consistent air/fuel metering which may feel a little smoother, better drivability and better fuel economy - sometimes these things can not be seen on a dyno and is just a feel thing.
If gaskets are free then try for an inch thick carb gasket to increase plenum volume, you will notice the difference ...
What car is it, Gemini?

Junior Sedan? Be very carefull especially if the car runs at the front.Cheapy,
It's a Datsun Sunny. The venerable little 1200 motor.
I have incorporated some other mods on the induction which have yielded significant responses. This one however seems at best, rather subtle.
