unknown headers

[krabysniper]

Big block headers, only identifying marks are the numbers 413 stamped into the flanges, nothing else 1 7/8" primarys, 3 inch collectors. Any ideas what they are for and or who made/makes them? I thought maybe they were for a truck but really don't know for sure. They bolt to big block heads.

They look more like van headers.

As the old saying goes "Everything is for sale, what will you give me for them?"
Thats why I was trying to find out what they are for is so I could get an idea of their value so's to sell them and get them outta my overstuffed garage. Give me a price of what you think they are worth and where you are located and I will get you a ship price if your serious.
