I apologize for the huge explanation but I have a weird problem.

I bought a house and the occupancy permit requires a fire door to be installed between the basement and the garage.  We were given 30 days to fix the door and a list of other things.  

The old door was only 29” wide by 75“ tall, had a “header” made of clay brick that was “supporting” a load where a flight of steps rest above. The opening in the cinder block wall is 33.5” wide and 86” tall.  A fire door with the jamb is 31.5” by 81.75”.  

I supported the loaded wall with steel beam and jack posts. I removed the door, knocked out the clay brick, installed 1x8 treated lumber to frame the doorway and installed the fire door.  I hope this at least gets us the occupancy permit.  Now I am not sure how to proceed after the floor joists are lifted back to where they need to be. 

To add to this situation, the top layer of concrete block is 8” by 4” but laying with the 4” side down so the block is 8” tall.  So, the header can only be 4” x 4”.

Any thoughts from anyone that has seen this before?
