the A and Z groups use a variety of different parts. the A group cover looks fairly similar, but there are some differences that I can see. if the Z group engines are like the ones in the A group (lots of cross-compatability), than that CRV one should be fine to use.
as for the block, i think the Z groups have the stamp in the same place as the A groups, which is on the front of the engine below the starter/next to the bell housing. removing the intake manifold may be neccesary to see it
