That's a lot of walnut.

If you see the nails, you didn't have a top tier installer. Also, one side of a room can be fixed without trouble. So consider this, tongues out form both sides. One course with a double groove. Drop it in with face nails in very few places. Again, incredibly rare to see face nails in a proper install.

Solid wood floors are milled with an expansion gap in the tongue and floor side.  The wear layer has no gap.  So the bottom 2/3s of the floor can move but the wear layer does not.  

 

Look at these photos.  The wear layer is flush but the tongue and bottom have an expansion gap.   This is 5/8" solid maple, 3/4" is no different

I am holding this upside down.   Notice the gap on the subfloor side, but the showside (which is the bottom of this picture) is flush

Nailing cleats are also designed to deal with this.  The bottom 2/3 or so of the clear is ring shanked, so it holds into the sub floor.  The top is smooth so the wood can move.  

Lots of guys use staples, because they are cheaper.  But staples can, and will, work themselves loose from the subfloor.

Also depends on species.  I'd guess 90% of site finished floors are flat sawn red oak.  It is incredibly easy to hide nails in the coarse grain.   Same goes for anything with a dark stain.  Natural maple, not so much.  Any trained eye can find the nail holes in a natural maple floor.  

Most guys also use adhesive on the face nailed floors so they can use fewer nails.

Yeah, but when do you use the canoe paddles? are those for stirring the adhesive or just for wacking guys over the head who point out the face nails?
