I take it you mean RedHat 6.x?

If you've installed the source, you should be able to read the instructions that come with it.

Usually the source will be installed in /usr/src/linux-.

Once in there, you need to do the following (from the 'README'):

make config (or menuconfig, or xconfig)
make dep
make bzImage (or 'lilo')
make modules
make modules_install

Depending on whether you made an Image or used 'lilo' will depend on what is required to be done to put the kernel in place.

You will also need to play with 'mkinitrd' if you didn't compile the root disk controller's drivers into the kernel (ie. made it a loadable module).

'man mkinitrd' is your friend.
