probably not.
the retainers you have are light anyway and you actually probably have enough spring pressure to keep the valve trane stable with that cam.
A bigger cam with faster ramps (CC 503, CC 306, GM 847, etc) would want more spring pressure than you have now and a better spring (bee hive or dbl)would be needed.
The light retainer CAN NOT make any HP but if the spring is on the verge of not being able to handle the cam, the weight of a steel retainer can push it over the edge and therefore end up losing power.
I would not buy them unless you plan on a cam swap and need them for some dbl springs.

So will the hotcam springs take almost daily beatings? I like to spin it up everytime I take the car out, hotcam'd motor isn't in the car yet, so I wanted to do whatever I could to it before I put the engine in. I guess I'm the personality type that will go WOT to hit a 50 mph speed limit would give a good idea what kind of abuse I'm worried about the springs taking. I realize the hotcam isn't a really high rev cam, but I want the margin of worry to be low on the valve spring side of things.

Plus to use the springs your talking about, the heads will need to be cut for the larger locators.
