A ported completion and method for use in fracturing multi-zone wells. A casing assembly having a plurality of casing lengths and one or more collars positioned so as to couple together the casing lengths. The collars may be a tubular body having an inner flow path, one or more fracture ports configured to provide fluid communication between an outer surface of the collar and the inner flow path, one or more valve holes intersecting the fracture ports, one or more valve vent holes positioned to provide fluid communication between the valve holes and the inner flow path, and one or more valves positioned in the valve holes for opening and closing the fracture ports. The valves are configured to open when a pressure differential is created between the fracture ports and the valve vent holes. The valve vent hole may be an annulus around the perimeter of the tubular body.
