300/340 Poston Headers Value?

I just got what I think is a great deal on a set of Poston 300/340 long tube headers, 150$ shipped off Ebay. What are these usually worth? They have several dents in them. Also is it worth putting these on my 67 300?

 

That’s a good deal yes, not too many of those floating around. Get em on the car

 

Can I purchase them from you?

 

I sold them about a year ago already.

 

I've been searching under ever rock going years back on every buick forum to find a set of these!

Any way the guy you sold them to wants to part ways with them??? Haha

Thanks for your response any way. It would be a miracle to find some of these now a days. Any help is appreciated.

 

Sanderson has shorties but no long tube.
