Differences between 96-98 cobra headers vs 99-04 cobra headers

[BMOREstang]

Alright now I realize that the 96-98 cobras had b heads and the 99-04s had c heads but are the exhaust ports any different?? I have done a gazillion frikn searches and I keep coming up with mixed answers. I heard that the only differences are the shape/where the egr is. What are the actual differences between the headers? lol I am going crazy trying to find an answer to this, thanks.

The exhaust ports on the "B" and "C" heads are the same. The difference may be in other places.

Page2 has a picture of the differences in the intake and exhaust ports. The exhaust are exactly the same. The difference is on the intake side.

My longtubes I bought were listed as 96-03 cobra longtubes. They fit my 01 just fine. They had a few extra bungs on the driver side tubes that I didn't use, they're there for the 96-98 cobra's I believe.
