I think the 04 heads are alot like cobra/mach heads. I have 01 navi heads on my 4.6 and it took some good manifold work to make it work and fit. The openings are bigger than the manifold opening

So the manifold will bolt on I just have to port it out?

I don't know exactly about the 01 cobra manifold but we had to modify the flanges on the heads to make it fit. People say it doesn't work but it does if you take the time and put in the sh*t ton of work it takes to make it work. It was worth it for my setup. But me and sweet2kstang spent alot of freakin time just to make that work.
