What header is this?
#2
#4
So don't think it's for an F3....
Stock header is the first pic, the one I got in the mail is the second. The guy said it was for an F3, but I don't think so. The stock header mounts flush to the cylinder head, and the flanges are flush. This new header mounts inside the ports, or fits somewhat inside the exhaust ports, and the flanges stick off the mounting holes about 1/4 inch. Am I missing something here? Or is this new part certainly not for an F3.
