As this is a custom compilation, I suggest you to add a custom tag that will identify the new kernel, to accomplish this, do that:

Select Local version – append to kernel release

Give the string value as  x86_64

7.       make bzImage

*The compilation will start, it will take a looong time.

8.       make modules

* The compilation will start, take a loooong  break

10. make modules_install

11. make install

*make install will copy the files: System.map, vmlinuz and the initial ram disk initrd-3.6.6X86_64.img to /boot. It will also add the lines you will need on grub, now just restart your computer and choose the new kernel on the grub screen.

12.  Edit the /etc/grub.conf and change the default kernel value as 0

13. Reboot
