om606 has a factory fuel/coolant heat exchanger build into the heads so I didnt have to worry. If yours doesnt I'd get one. I also have a 12v sillicone heating pad wrapped around my fuel filter to help warm it up before the engine has got to temp.

Mine should have a fuel heater, but as far as I know, it's been removed.. the joy of old cars with multiple owners and no service history
I may try something petrol in it if the filters have no impact.
