IMO this engine seems to have a lot of resistance to cooling solutions.

The best way? Yes. This is how engines are developed for race cars, except they're in a test cell with a controlled environment (even the air going into the engine intake can be 100% controlled: composition, humidity, temperature, etc.).
Is this how all aftermarket manufacturers and FI kit manufacturers do it? No.
I can say that the Jackson Racing kit and tune was developed using a dyno like the one pictured above (it was actually the dyno one bay over from the one pictured; this facility houses 5 sets of dynos).
A dynapack allows for a full range of tuning. For example, under normal driving conditions, you could be at 3000 RPM with 0 throttle (decelerating), light throttle (cruising), medium throttle (easy acceleration), or full throttle (WOT!). The dynapack can hold the engine at 3000RPM, and allow you to go through the *entire* range of throttle positions, from 0 throttle to full throttle, and tune for the entire range.
