Hi Milton,
Underside of hood should be black.
Most of the nuts/bolts will be green - unless an accessory or component was added after the engine was painted (by the factory).
You'll need to reference photos on that.
Steel brackets are green; I believe aluminum brackets are bare alum.
Water pump should be green. Don't know about the fuel pump, I left mine natural.
Hood latch should be gold zinc/gold irridite.
