You're right that IF the metal calorimeter and the styrofoam calorimeter were both perfect and behaved in the way that we usually pretend calorimeters do (they don't absorb or lose heat) then they should produce identical results, for the enthalpy reason you provide.
Whaine wants to make plaster molds of the styrofoam, not use the styrofoam for making a mold. You might consider coating the pieces with a spray on polyurethane coating, giving it several layers, to seal the cracks and crevasses that styrofoam has.
