Your kernels look fine actually. All kernel images have that large
collection of attention-grabbing strings, they seem to be regular
compiled in error messages. And the version numbers are fine.

I've just built 3.13.1-gentoo here and my perms come out right, so it's
not a bug that e.g. snuck into that one version's Makefile. And I know
of no way for a bootloader to influence what a kernel image thinks it's
version is or how to get to it's modules (it would be a huge attack
vector if a bootloader could do that)

I think I'm all out of ideas now, you might have to consult with some
kernel guys. Per my understanding, what you describe cannot happen, so
it's an odd one indeed.
