'93-'95 Cobras all had them from the factory with GT40 heads and stock 5.0 valve covers.  They were 1.72:1 ratio made by Crane as I recall, though they had a Ford part number stamped into them.

Pedestal mounted using the same weak 5/16" Allen head bolts.  Ford didn't want to spend anything on the Cobras, so they used as many stock GT parts as they possibly could.  The director to SVT, John Coletti, wanted the big brakes on the Cobras and Ford wouldn't give him the money to do it.  He literally paid for it out of his own pocket.  Imagine the Cobras without the big brakes!  Proof positive that every auto executive isn't a bean counter.  Some are indeed real car guys.

Anyway, as to whether or not the '84 valve covers will work I can't say.  I know the cast aluminum ones used on the later GTs and Cobras will work.  If you get stuck and need a set I'm pretty sure I have two sets up in the shop.  If you can take measurements on the valve covers you have from the gasket mounting surface to the top of the cover I can measure a set I know will fit and we can see if the ones you have should work or not.

I'm wondering if there's a difference between the factory ford rocker arms versus the aftermarket ones?  It's been years since I installed a set of ford roller rocker arms but I can't help but think the overall profile is different than the aftermarket ones.

I am running the 82-85 HO finned valve covers on a 94 Cobra 5.0 in my 67 coupe no problems. I used the Ford metal gaskets.

do you have roller rockers on the engine too?

The Ford ones are exactly the same as Crane Energizer (aluminum bodied) roller rockers, as they were made by Crane for Ford.  The only difference is the Ford ones have the Ford part number stamped into them and the generic Crane ones do not.  Deviate beyond Crane and there's no guarantee they will fit under stock cast HO valve covers. 
 

I have “Cobra” valve covers as were available in the 60’s, and COMP Cams Aluminum Rocker Arms #17043-16.   I modified the valve covers as seen in the pictures to preclude oil being flung into the openings for the PVC and breather openings. 
 

This is the setup I used on my 351W with the 5.0L GT40 heads. Crane roller tipped rockers. I use the finned aluminum valve covers with a extra thick cork valve cover gasket. I also modified the oil baffles by relieving some material from the four raised bosses in the cover and custom bending some thin stainless steel to fit. It all has been working fine for 17 years now. (I had to go back later and replace the weaker 5.0L valve springs with stiffer ones due to valves floating at higher rpms)
 

Yes I have the roller rockers and roller cam. I use a second oil cap with the pcv in it. I have never had any problems with this set up. It is all stock Cobra parts in the engine..
