Yes, the package is usually called <kerver>-dev.

I'm not sure exactly where that one's coming from.
Hardened kernels were dropped (because grsec went private), and the last 
available package (as far as I can tell) is 4.9.65-r1 - a lower version.

Summary:

- linux-headers don't have a -dev variant, and are the headers for 
interacting with the kernel (in /usr/include)
- kernel artifacts such as above are in a <kerver>-dev package
- you appear to be using a relatively old kernel, which does not have 
KPTI (that was added to the 4.9 line in 4.9.75), though my understanding 
is that grsec patches (as they were pre-private) aren't compatible with 
KPTI.
