World Products Small Block Ford Windsor Jr Cast Iron Cylinder Heads

Bolt On To Your 5.0L Mustang With No Loss Of Compression!

The World Products Windsor Jr. head features 180cc intake runners that combines high velocity and superior flow to produce excellent torque and throttle response in stock to mildly modified 5.0L engines. The 58cc combustion chamber is sized for true bolt-on compatibility, and has been ''tweaked'' to optimize efficiency. Windsor Jr. cast iron cylinder heads provide a very cost-effective solution to getting serious power from a Ford 5.0L motor without spending a ton of money. And when it comes to value, you can't beat the assembly packages from World. Top grade components, like Erson stainless steel valves, are used as your assurance of relability, with World passing bulk buying advantages right through to customers. If you're looking for a cost-effective, bolt-on cylinder head that works, the Windsor Jr. is for you!
