Everything is from CentOS including the kernel sources. I downloaded the SRPM and modified the spec file to %define buildsource 1 then did an rpmbuild. Then I installed the kernel-sourcecode rpm that it generated. So then I could run the kernel config from /usr/src/linux-<version> and then build a custom kernel.
