I have a 396 BB in my 67 Camaro and wanted to ask everyone or anyone that would have any idea what Brand headers I have. The only # I can find on the flange is 1004. They are 1 3/4 with 3 inch collector. I want to be able to use the same headers. I'm not sure how old these headers are but I think the part # is an old number. I have sent emails to all the header manufactures to see if anyone know. Please help!!!!!

Thanks

I think that is a Hooker part #
