These Ford Racing 'Z' wedge-style cylinder heads are cast from A356 T6 aluminum and CNC-machine the combustion chambers for consistency. They feature high-flow ports, steel-alloy intake and exhaust seats, manganese-bronze guides with semi-finished IDs, and include laser-cut guideplates. Intended for competition use, they accept tapered-seat and gasket-style 14mm spark plugs.
