What's in the Box


Jack Roush Racing designed this high density cast iron head to be the most powerful head for 5.0 Fords. When it comes to high performance replacements for factory cast iron heads, World’s WINDSOR SR. boasts 200cc ports and 64cc exhausts ports, which flow a substantially larger volume of air than any OEM Ford head. Add a highly efficient combustion chamber design and larger valves, and you have big bolt-on power! This head is also a 50-State emissions legal factory replacement.

This particular head comes assembled with flat tappet springs. They can be used with a racing solid lifter camshaft, or they could also be used with a hydraulic roller camshaft. Using them in conjunction with a solid roller camshaft would require changing the valve springs on the heads.
