You can add kernel sources to a set so they are never depcleaned

% cat sets.conf 
[kernels]
class = portage.sets.dbapi.OwnerSet
world-candidate = False
files = /usr/src

Then emerge -n @kernels

I do the same with gcc so I can keep the previous version

[gcc]
class = portage.sets.dbapi.OwnerSet
world-candidate = False
files = /usr/x86_64-pc-linux-gnu/gcc-bin
