Ford Racing Z-Head aluminum cylinder heads engineered for Ford 302 and 351W small-block engines — fully assembled with 63cc combustion chambers and precision-fitted 7mm valves for optimal airflow and performance.

Description

Cast from prime A356 T6 aluminum, these ‘Z’ heads from Ford Racing were designed using solid modeling technology. They feature high-flow ports and steel alloy intake and exhaust valve seats installed (they do require a competition valve job and bowl blending). The manganese-bronze valve guides are installed with a semi-finished I.D. and the combustion chambers are CNC-machined. Laser-cut guideplates are included, and they accept both tapered seat and gasket-style 14mm spark plugs.
