A gasoline manifold has a "hot spot" at the top of the carburetor leg. It is heated by hot exhaust gases in the exhaust manifold. Its purpose is to evaporate gasoline droplets leaving the carburetor before they enter the cylinders. This improves combustion under cool conditions. The downside is the heated gas/air mixture results in a slight loss of power (warmer fuel/air mixture = less power).
An LP manifold has no hot spot. It is not needed since the fuel is already a gas when it enters the carburetor.
Pullers like the cold manifolds since they'll give a gasoline engine a little more power. But a cold manifold on gasoline also gives poor running in cold weather/high humidity unless an auxiliary heater is provided (manifold stove, etc) to warm the inlet air ahead of the carburetor.
