Cobra manifolds require steering shaft relocation, as well as caping off the air injection pump fittings. If your looking for a decent manifold without air injection fittings then you'll need ones off of a 93-95 mark viii. As far as porting gen 1 mark manifolds, good luck, there isn't much material to be removed. Of course the only high flow direct fit option is kooks for a gen 1 mark.
