While looking back through the book of reciepts my car came with I found one that said Used Headers 930 from BPK in NYC for $700. I am wondering if they were used stock headers or aftermarket headers. All I know is they do have heater boxes, is there a part number somewhere on factory ones? Or something obvious I can look at to tell??

Thanks!

just found a pic of a euro stock header and I think that's all i have. Is there a hp upgrade between aftermarket headers and euro headers still?

My 77 930 has a factory tube header with no cat, its a Bischoff brand and I would like to find out more about it. It also has heater boxes. Jamie
