The OP should read the section of the Gentoo manual on kernel install to learn what files are installed where. Yea, but just rm the kernels and initramfs's from /boot and you're golden. FWIW, I usually only upgrade my kernel when it's a major revision.

As far as I'm aware, depclean only installs files it installed, so it
leaves quite a lot of garbage lying around from kernels, including the
/usr/src/kernel-xx-xx-xx directory and various files involved in making
your kernel, that you've modified.
