I need to downgrade the kernel from 2.6.32-358.6.2.el6.centos.plus.x86_64 to 2.6.32-220.el6.x86_64

I am unable to install the older version using Yum/rpm as it gives the following error

root@localhost kernels]# rpm -i --ignoreos kernel-2.6.32-220.el6.x86_64.rpm 
warning: kernel-2.6.32-220.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID  
192a7d7d: NOKEY
package kernel-2.6.32-279.el6.x86_64 (which is newer than kernel-2.6.32-220.el6.x86_64) is already installed
package kernel-2.6.32-358.6.1.el6.centos.plus.x86_64 (which is newer than kernel-2.6.32-220.el6.x86_64) is already installed
package kernel-2.6.32-358.6.2.el6.centos.plus.x86_64 (which is newer than kernel-2.6.32-220.el6.x86_64) is already installed

I cant remove the currently running kernel , so whats the way out?

Yum search doesnt even get me to this old version, so had to get the rpm from web.

Any help is much appreciated.
