No header gets modified. Instead, a new header gets prepended.

Actually it's pretty stupid to use a zImage inside an uImage. It is
much better to use normal (uncompressed) kernel image, compress it
using just gzip, and use this as poayload for mkimage. This way
U-Boot does the uncompresiong instead of including yet another
uncompressor with each kernel image.

You can boot zImage files directly with U-Boot. That's what the
"bootz" command is for.
