World Products Ford Windsor Jr. & Sr. Cast Iron Heads

One of the keys to extracting maximum performance from cast iron cylinder heads is combustion chamber work. The Windsor Jr. / Sr. combustion chambers are much improved over factory Ford heads.

The stock World Products Windsor Jr. 180cc runner heads will flow 226 cfm on the intake side and 144 cfm on the exhaust. With our “Undercover Porting” the intake air flow improves to 244 cfm while the on the exhaust side air flow will jump to 161 cfm.

The World Products Windsor Sr. 200cc runner head will flow 242 cfm on the intake side and 154 cfm on the exhaust in stock form. After our “Undercover Porting” the intake will flow 255 cfm and the exhaust will improve to 170 cfm.

From “Undercover Ported” to CNC Sportsman Ported, we offer the World Products Windsor Jr. and Windsor Sr. Ford cast iron heads anyway you want them. And yes, we will also rework your heads!
