Sometimes the heat from the exhaust manifold will cause the gasoline
in the carbs to evaporate after you've parked the car. When
restarting you have to crank for awhile to pump fuel to the carbs.
One solution for this is a heat shield between the carbs and exhaust
manifold. Another solution is an electric fuel pump.
You mentioned that the engine was sluggish turning over when hot
starting. Electric motors do not like heat. Has your starter been
overhauled? Bad brushes can cause sluggishness. Worn or corroded
contacts in your starter solenoid will cause a big voltage drop across
the solenoid, resulting in the starter turning too slowly; if this is
happening, the solenoid will be VERY hot, often hot enough that smoke
will rise off it. In both cases the battery can be fine but appears
weak. A new solenoid is a cheap and easy repair, try that first.
Is your cooling system working properly? If the engine is running
too hot, it will aggravate all the above symptoms.
