Valve covers get a lot of heat from being doused by hot oil. Some of them are even finned to help reject more heat- not just for appearances.

Excess heat can weaken valve springs. If the engine tends to run really hot I would be wary of this and monitor temps closely. If you p&g a lot this could really keep the heat in.
