The gaps are almost entirely found at the bottom of the card, similar to the one above. Exceptions would be cards with a horizontal layout. I have 24 of these gap cards in my collection.
As for the Kaline card, I hadn't really thought of the comparison before now. I would say that they are different in that Kaline actually HAD the bandaid on his head in the original image and Topps airbrushed it out in later print runs. The Griffey "bloody scar" appears to be an inking issue on the printing plate (although admittedly haven't looked at the Griffey cards in some time)
Always looking for baseball variation/error cards and anything Garrett Whitley or Ian Anderson
