If you can believe NGK they claim a DPR8EA-9 fits the 1986-87 VFR400 (NC21)and a C8EH-9 a 1987-88 VFR400 (NC24), both 0.9mm.

looks like you cannot believe NGK.

C8EH9 is the correct plug for the nc21 and nc24. (that is going from my honda service manual), out of all the nc21's / 24's i've worked on, none of them have ever has D plugs, I think they'd hit the valves.

0.8mm plug gap.
