Any reason why the 4v wouldn't work ? Aside from the throttle body inlet ? I've ran 2v headers on 04 cobras
I think the header location relative to the K member is the same. I know that square port 4v header flange will massively leak on a 2 valve. I ordered some Basani Mid Lengths a few years back and they were miss packed the headers with two 4v header tubes. I didn't notice during install...the leak was horrific. Good to know 2v to 4v works and fits...I guess re-flanging could work if you knew a good fabricator. Not willing to test the waters unless I got an amazing deal on the headers.
