366 TDBBC "High Perf" Heads?

When I had intentions of building a 366 for my truck (hey, it was free), I noticed that the factory heads had a high performance stamp on them. Isn't this kind of odd? Or is it due to the rigidity of the valve springs, rocker arm studs, etc? Beats me. This was out of an 88 C60, it was carbureted from the factory. I don't have the engine anymore, but I was just curious about this. Thanks.

Steve
