Oh. Ic. Yes, ish. The cobra heads 96-98 flowed a little better than the 99 cobra, the 01cobra a little better than the 96-98 cobras, and the 03-04 cobra/mach1 heads the best of the bunch.
The 99s had something wonky from the factory and there was that huge recall for lacking hp. Oddly, when 96-98 intake cams are used in the 03-04 heads there are small hp gains.
Im not sure but the 2000 cobra R
heads may be the same as the 03-04 heads but don't quote me on it.
