To be honest I did this recently on F19 and found that the build
process (after git checkout, copy config) went like:
As normal user:
make oldconfig
make -j4
(well, j3 was better for me, but this is from the example
http://wiki.gentoo.org/wiki/Kernel_git-bisect)

As root:
make modules_install
make install
(most guides don't mention you only need root for the install steps)

And this did the dracut for me fine, the kernel also showed up in the grub menu.
What would be nicer to see is dealing with cleaning up the previous
build kernel which seems to get left out. So far as I can see this
requires:
remove from boot the matching initramfs, System.map and vmlinuz
run grub2-mkconfig -o ... (removes old entry)
remove the corresponding /lib/modules/3...
