You can just leave the updated kernel-headers.  I have kernels back to 
2.6.20-1.2925.2.5.fc6.netdev.7 (not a stock kernel), including the stock 
2.6.20-1.2933.fc6, and only one kernel-headers-2.6.20-1.2944.fc6.  kernel 
RPMs don't even depend on kernel-headers anyway.

$ rpm -q --requires kernel-2.6.20-1.2933.fc6
rpmlib(VersionedDependencies) <= 3.0.3-1
fileutils
module-init-tools
initscripts >= 8.11.1-1
mkinitrd >= 5.1.19.0.2-1
/bin/sh
/bin/sh
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1
[mjs at vincent52 str-plan]$ rpm -q --whatrequires kernel-headers
glibc-headers-2.5-10.fc6
glibc-headers-2.5-10.fc6
[mjs at vincent52 str-plan]$ rpm -q glibc-headers
glibc-headers-2.5-10.fc6
[mjs at vincent52 str-plan]$ rpm -q --requires glibc-headers
/bin/sh
glibc = 2.5-10.fc6
kernel-headers
kernel-headers >= 2.2.1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
