I already have the Zerostart 3100039 600w Block Heater. I had considered adding another heater, and according to the site below, the Zerostart 3100040 600w Block Heater will also work; it's just for a different location, and it's aimed at 7 o clock instead of 6. How fortunate?

Why would I want that? Well, I want more heat at launch in the dead of winter. Only one 600w heater isn't a whole lot, that'll just take some of the edge off. It'll likely get me above the freezing point, but it's just better to have two in Pennsylvania Winters.
EDIT & UPDATE: I looked at photos of the Ford 4.0 Engine, and it seems as though
this won't work. There doesn't seem to be another freeze plug on the engine. If I find another one on just this car, then I'd like to get another heater. Otherwise, no.
Also, "Oil Pan 4" has posted this experience about using two 600w heaters:
"This one is easy.
Install a second stock engine block heater or find your vehicles stock heater, get 2 of them and install.
What does that do?
You might think it wastes double the power.
It actually saves power. Instead of leaving the standard single 600 watt heater plugged in all night I have found that you really only need about two hours with double block heaters to reach close to the same level of heat you get running a single block heater all night."

Also according to the ShowMeTheParts site, I can apparently buy an Oil Pan / Transmission Heater (Zerostart part 3500047,) but that seems a bit much; it's $115 on eBay, for one. Besides, Oil Pan 4 provided a guide for how to do that as well (linked below.)
