It seems that you are not running the newest edition of the kernel?
Is there any specific reason for this? If not try running:
su -c 'yum update kernel*'
To update to the newest kernel.
Then reboot, install the kernel-headers again and run make again.
If you have a reason to stay with the older edition of the kernel you must download and install the package manually. Link to headers
for your kernel(If you use 64-bit, be aware that you must get the 64-bit edition):
And then install it manually.
