Are you going to operate it with grid positive to cathode? If not, you
don't need Rgk. If you are going to, you will need to find a
characteristic for grid current versus positive grid voltage, or
actually measure it. From that you can calculate Rgk.

No, grid will not get positive to cathode. Can I delete Rgk from the
subcircuit?
