No prob.

I never run a heat crossover.

Some folk run into carburetor icing conditions at 30-50 degrees fahrenheit on humid days, due to the refrigeration effect of atomized gasoline, but I've never had to deal with this.

I drive year round in Minnesota without a heat crossover. Modern gasolines which contain some alcohol tend to be fussier with heat crossovers (vapor lock after turning off engine) and so tend to run better without them.

Make sure you disable the heat-riser valve on the passenger side exhaust manifold before you block the crossover, if your car happens to have one. THey are easily identified by a ribbon spring and rotating counterweight immediately below the passenger exhaust manifold.

JMO,
Shoe.
