i made the comment about blowing a rod through the block because youd think that if there was THAT MUCH MORE metal between you and the outside of the block, it would be more difficult to put a hole in the block.

Just at the top. You still have a water jacket between the block casting and the sleeve, even if the block is closed deck.
