They also modified camshaft profiles and replaced the variable runner-length intake manifold with a fixed runner-length intake manifold that year. In 1999, engineers updated cylinder heads and incorporated tumble-style intake ports, which feed two intake valves from a single intake port. Each intake valve has its intake port on the four-valve heads from 1993 to 1998. There are two inlets and two exhaust valves on each cylinder. Only aluminum blocks were used in the 32-valve 4.6L DOHC engines (except 2003-2004SVT Cobra, which had an iron block with 4-bolt main bearing caps).
