cast iron headers 400 sbc, worth anything?

[cib101abn]

Greetings all,

I have a set of OE cast iron headers that came off a sbc 400; when I heard the truck running didn't hear any exhaust leak, however inspecting the headers now that they are off and cool, notice some small cracks at the "Y's" in a few places, don't appear to go through as there is no discoloration there from carbon or exhaust gases...does this make them junk? I know cast iron can be welded but not sure about his application or leave them as is, was thinking of putting them on ebay but don't want to spend fees for something that won't sell..also one stud is broken at the doughnut connection, would need to be drilled out. thanks for any input. bob
