This is a pair of top and side rocker cover gaskets for all 6 cylinder Rover P4 and P5 models with the Weslake head (i.e. P4 110, P5 (3 Litre)  MkII and MkIII). The original Rover number for the top one was 521523 (superseded to GEG 434) and 274817 for the side one (superseded to GEG 433).

They are also used on the rare North American Dollar Area (NADA) versions of the 6 cylinder Land Rover which also used the Weslake head.

If you need the top rocker cover gasket on its own, we have them available in another listing (search for Rover GEG 434).

If you have any questions please ask.
