Crazy 454 Spark Plug SHOOTOUT!

[savatreatabvr]

What are the best spark plugs to use in a mid 70's 454? I've heard the cheap ones are just about as good as the expensive ones? What I want to know is how good is a set of $103.92 spark plugs? Especially when I know a set of $15.92 will work fine!
Is it really worth spending the extra $88.00?
