Nearly everything is based off something else. Lets face it, an alum smallblock Mopar head, is an alum smallblock Mopar head. There may be slight variations or better quality castings and machine work, but it is what it is. Maybe the ones in question are a direct copy of an Edelbrock, maybe their not. You would need to digitize it to know. But where did Vic himself get the idea, he sure didn't engineer it from scratch. If it's an EXACT copy of a factory head, except in aluminum, I guess we could say Vic "stole" the design and cast it in alum

As far as buying American, that's great, but if you ONLY buy American, you don't own a TV, a cell phone or basically ANY electronics or home appliances and many other things
