I have been making custom kernels for a while, never on 
RHEL, but I would think the process would be the same since 
I use the instructions from the kernel source. On Fedora, 
once I have done:
make oldconfig
make xconfig

I do:
make binrpm-pkg

which creates an rpm with the kernel image and the modules.
Running RPM to install the new kernel puts everything in the 
right place except for making the initrd.img and editing 
grub. If you are doing a lot of installs then I would make a 
script to do the last two.
