[CentOS] How to get unrelease kernel, e.g. 3.10.0-341.el7

Hi,

I cloned https://git.centos.org/r/rpms/kernel.git and found that it
only contains kernel version that CentOS released. So how do I get
the kernel version that CentOS not release officialy, e.g.
3.10.0-341.el7 and 3.10.0-383.el7 (some kernel version I found
in kernel.spec's changelog)?

Thanks.
