- World Products Windsor Sr. 5.0 Ford Cast Iron Cylinder Heads
The Most Powerful Head Designed For 5.0 Ford Applications!
Actual flow bench and dyno testing confirms that World's Windsor Sr. 200 cast iron heads are more powerful than the competition. It's also important to know that due to World Products RightCast technology and CNC machining expertise (all heads are made to rigid QS-9000 specifications). The Windsor Sr. 200 head is compatible with all standard-type pistons. What's more, efficiency is so good that they're covered by C.A.R.B. EO #D-343, and fully 50-state legal. To achieve the optimum power potential from World's Windsor Sr. 200 heads, you'll need an improved intake and exhaust system, more aggressive camshaft, and upgraded ignition system. It's absolutely the most potent head in its class for the 5.0L! Works with stock type piston designs, and does not require changing pistons to obtain combustion efficiency.
