Fresh Install 64 bit Snow Leopard on Early 2011 MBP

Quick question. I bought a SSD and will be doing a fresh install on my early 2011 MBP with Snow Leopard using the disks it came with. Do I need to do anything special to ensure that the 64bit OS of Snow Leopard will boot up every time?

I understand that the 64bit was loaded by default when it came from the factory. Did not know if the 32bit ver was there too and how a fresh install is treated on my early 2011 MBP. Will a fresh install detect my HW and loaded the 64bit by default?

Thanks,

Nope, when I did a format and reinstall it came up 64bit. The disks that come with it, btw, are hardware specific.. so it doesn't need to detect anything.
