What's It Worth - Slant 6 Headers?

74ChargerSE said
I have a nice set of headers for a Slant 6 to go with a Super 6 2bbl Intake I previously listed For Sale. Any thoughts what the Header is worth? First one I have seen.

New or used? What make, long tube, or short tube, body style, G motor, or RG? Pictures? need more info
