NOTE:
Early build engine cylinder heads and fuel injectors differ in design than late build engines. Although these parts are serviced in the same way, the parts are not interchangeable between early build and late build engines. The level of cylinder heads and fuel injectors can be determined by inspecting the engine code label. Early build engines are built through 09/14/2010 (0S 490 BA) and late build engines are built on or after 09/15/2010 (1S 490 BA).
