The suzuki guys are correct. More resistance = less heat. Think of heat as the volume of water in a pipe. If you add a restrictor, you're reducing the volume of water, therefore reducing the amount of heat.
Heat is a function of current (since the the max voltage is fixed).
Ohm's law states I=V/R. Increase R, I decreases.
If you want max heat, wire them in parallel. Keep in mind, in a parallel circuit, equivalent (or apparent to the battery source) resistance is closer to the lower resistance than higher. For example, 10 ohms and 10K ohms are in parallel, equivalent resistance = 9.99 ohms. (product over sum formula).
