Question. Are 70 Six Pack outboard carbs rare or valuable?

I ran into a deal on a 340 manifold and carbs. The center carb is a replacement with no serial numbers. The outboard carbs are 1970 4382 and 4383 serial numbers. They need cleaned up, a few pieces and rebuilt. I'm just wondering if they are better off with someone restoring a six pack car or if the market is flooded. I don't need the numbers for my build and can use replacement Holley's. Will these be of value to a restorer or should I just clean them up and run them?

Thanks for the info guys.
