I picked up this tip some years ago to avoid depcleaning kernel sources.

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

and emerge -n @kernels

I also have this in the file to allow multiple GCC versions.

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