Dougs Ceramic Headers small block

Bought these for my stroker build, but I had a bad block.
These are new, still in the box. Part number D453 ceramic coated long tube headers. For a,b and e bodies with small block.

Headers are in Adairsville GA
Paid $700, I would like to get $600 for them. I get good rates on UPS shipping.
