Exhaust rocker cover
Exhaust-side rocker cover for the cylinder head, part number 70-4649 (formerly E4649).
This is the exhaust rocker cover, part number 70-4649, listed under the older E4649 designation in earlier parts books. It sits on the cylinder head, capping off the rocker box on the exhaust side so the rocker gear underneath stays enclosed and oil-tight.

The catalog places it in the cylinder barrel and head figures, which is exactly where you'd expect a rocker cover to live. Our records show it appearing across catalog entries from 1963 to 1964, but we don't have more detail tying it to a specific model beyond that.
If you're replacing one of these, check the gasket surface for warping or old sealant buildup before bolting the new cover down, and confirm the fitment against your own head before ordering.
