"Dry deck" = no coolant passing through the deck of the block, past the head gasket, to the heads. It aids in head gasket sealing on higher HP applications, especially when a power adder is used. Coolant is typically rerouted at the back of the block to the back of the heads via braided lines and fittings. Hard to accomplish with a factory block, but the IA-2 block comes delivered with a "dry deck" unless specified when ordering.
