If you mean the tappet/cam follower covers - there are no tappet/cam follower covers on a 1275cc 'A' Series. The N/S of the block is solid therefore no covers. To remove the tappets/cam followers you have to remove the camshaft.

The question above was in relation to the 1275cc Marina/Ital engine - but to clarify - the 1275cc classic Cooper S block does have cam follower access openings with covers.

Only if the head studs have a point, a dimple or a 'Y' on their top the torque setting is 50lbf ft.
