You probably don't need to install the devel package unless you plan to also build third-party kernel modules. You shouldn't need to install the headers package. The content of that package *should* be the same as the one that was provided by the vendor (CentOS), and if it is not then you would need to rebuild glibc in addition to replacing them. The same is true for "make headers_install": It shouldn't change anything, and shouldn't be necessary.
