What do you do to winterize your drag car?

I'm fortunate to be able to store my cars in a heated shop, so I don't do a whole lot.
I drain the fuel system (alchohol) & flush it with WD40.
Unbolt the the rocker shafts to unload the valve springs, after warming the engine.
Pump up the pressure on the tires.

In the spring time, I change the oil, trans & axle fluids.
Bolt the rocker shafts back on & set the valve lash.
Flush the WD40 out & run the car with a gas carb, before I switch it back to Alcohol.
