Give a nice flat mosfet package and a flat heat sink,

There is no such thing as flat. There is only different levels of
rough. Extremely flat is extremely expensive.

In theory, when you bolt two metal object together, they will only
contact at three microscopic points.

We always put some solder onto the tip of the soldering iron before
soldering. Otherwise the heat will simply not transfer to the
workpiece, even if both the soldering iron and the workpice are flat.
