When I do this I like to install my kernel to a custom directory

make installkernel KERNCONF=whatever KODIR=/boot/foo

Now the kernel goes into /boot/foo

You can ensure the system uses this kernel at boot by putting
kernel="foo" in /boot/loader.conf

You can also put kernels="foo,bar,baz" in loader.conf if you want the
boot menu to have those kernels listed as options.
