Livernois Motorsport's is one of the top 4.6L and 5.4L Ford Modular engine builders in the world. We took a trip to Livernois to check out their new offerings of 3-valve 2005-up Mustang cylinder heads. Available in separate different stages, from mild to wild, these 3-valve heads are CNC machined and are capable of anything from 400 hp to 1,400 hp, depending on your specific engine and power adder combination.
