How come you're selling original type parts to replace them with an other than original look? Just curious.
I bought the chrome pent roofs for mine along with the turkey pan and Stellings air cleaner. Didn't like the chrome job on the valve covers, so had them redone. Only the tops were decently polished. After redoing, they looked pretty good. (see gallery)
I should note that I also used an orignal Shelby sidewinder manifold with the
oil fill tube, so I didn't need (or want) vented valve covers.
BTW 427 S/C Cobras never came with aluminum valve covers that I ever saw or heard of. That's a Mustang thing.
