World’s S/R cylinder heads are the preferred alternative to expensive OEM castings or junkyard rebuilds. These heads are designed with extra-thick decks and walls for improved reliability as well as equipped with hardened steel exhaust seats that are compatible with today’s unleaded gasolines.

The Sportsman's 200cc intake port offers great throttle response and torque at mid-range rpm for stronger acceleration and performance off the corners. Available with 64cc and 72cc chambers for compatibility with factory chamber sizes. The Sportsman II is specifically designed for maximum performance with flat tappet or hydraulic roller camshafts. It is ideal for dirt track cars, street cars and boats.

The innovative chamber design achieves excellent low-lift airflow by un-shrouding the valves, and the multi-angle intake valve seats produce improved fuel atomization for better combustion efficiency.

The cast iron MERLIN rectangular port design is available with intake ports in 320 and 345cc configurations. Choose the port size that will provide the optimum balance of flow and velocity for your engine combination. The 269cc oval port design provides great low to mid-range power and throttle response for street and racing engines up to 496 cubic inches.

When it comes to high performance replacements for factory cast iron heads, World’s WINDSOR SR. boasting 200cc intake ports, plus 64cc exhausts ports that are substantially larger than OEM Ford heads, suitable for larger displacement and high RPM engines.
