408 - Crank hitting dip stick

I asked on the other thread and didn't get an answer so I'll ask again. What's the difference between the Milodon and stock replacement dip stick, besides the fancy billet handle? They would have to be the same length to read properly correct?

I've been reading everything I can about stroker small blocks for ten years now, and all of the sudden stock dip sticks are no good?!?
