The kit instructs you not to socket it because the PCB has a lot of uninterrupted copper serving as both a ground bus and a heat sink.  Socketing the IC will leave the ground pins with less of a physical connection to all that, making it a less effective heat sink.

When I want to add a heat sink to an IC like this one, I use a clip-on one with fins, Mouser part number 532-580200B00.
