Headers What Kind?

I am looking at selling these ceramic headers in the near future, but I cannot tell what brand. Does anyone know? Does anyone know what I should ask? They do have a few scratchs, but they never been used. They came with my 305 so I am ***uming they are set up for a sbc. I want to set a fair price for both myself and the buyer Thanks

 

Those look like the Hedman "tight tubes" with that flat 4 into 1 collector. More expensive thant he standard block huggers with a square 4 into 1 collector.

 

They kinda look like ****** huggers for a sbc.

 

What do you think would be a good asking price? They are not perfect, they have a few blemishes, but not dents.....

 

I looked under ****** but didn't see this set. My friends are sure its Sanderson Headers

 

I'll give you $30 for them.
