A block heater might be your best bet, both oil and cylinder temperature are your best bet especially when relying on cylinder temperature for ignition.

Yes I agree! I believe I an intake heater is optional for these engines also.

A fuel preheater is a good option especially if you add an air intake preheater as well it's nearly guaranteed to start in all temps with those the block preheater will aid in ease of cranking as well not ease of starting though but the best mod for these engines is the electric start and charging systems for year round use and can be had for under $125.
