Depends upon what you're shooting for. An open deck allows for a more free flow of coolant around the cylinders, but a closed deck is stiffer and can handle more abuse from pistons that have more off-axis loads. Open decks are often easier to cast, but they're also often not as accurate tolerance-wise.
