Ford Racing 302/351W Z-Head Aluminum 63CC w/7mm Valves

Over the years, racing has become big business for teams, sponsors, and manufacturers around the world. However, 'grassroots' motorsports remain at the core of Ford's DNA. Grassroots performance began with Ford and has become a part of American culture. The Model A is the most modified car in history, and enthusiasts the world over continue to embrace Ford, Mercury, and Lincoln cars and trucks from the 1930s right on through to today. Road racers, drag racers. circle track competitors and street rodders have channeled, stepped-on, hopped-up, chopped down and modified their favorite cars to excel on the street, at the track, and in car shows. The Ford Mustang immediately became part of this culture when it was introduced in 1964-and remains a staple of grassroots performance to this day. In 2014, Mustang marks 50 years of winning, and has driven its way into racing history. Moreover, the car's appeal is universal

Product Overview

; a recent European study identified Mustang as the most desirable classic car in Europe. Motorsports continue to evolve, with advances in technology and greater demand for smaller powertrains, as well as growing appetite for new formats like Rally Cross and Drifting. How it develops in the next 50 years remains to be seen, but we intend to be there to celebrate it, thanks to passionate enthusiasts like you, who have driven the success of Ford, Ford Racing and Mustang since the beginning.

Ford Performance Parts Z-Series aluminum cylinder heads provide increased intake and exhaust airflow and are available for Ford small block Windsor engines. They were designed using solid modeling technology from prime A356 T-6 aluminum and feature high-flow ports, steel alloy intake and exhaust valve seats, and manganese-bronze valve guides. Ford Z-Series heads accept both tapered seat and gasket-style 14mm spark plugs and are available as-cast or CNC-ported, both bare and assembled.

Select heads are also offered with advanced "Velocity Vane" intake port design that delivers outstanding street/strip power. Developed with advanced computer-aided engineering simulation tools, their unique intake port design improves power throughout the rpm range. Velocity Vane cylinder heads are a direct bolt-on and retain OEM exhaust, intake, rocker arm, and accessory mounting locations.

Features include (some vary depending on version):
• A variety of combustion chamber volumes
• Cast with high-flow ports
• 20 degree inline valves
• Steel alloy intake and exhaust valve seats
• 7/16 in. screw-in studs (not included on bare heads)
• Requires 1.5:1 ratio roller rocker arms with .150 in. offset intake pushrod cup (not included)
• Assembled heads include laser-cut guide plates for 5/16 in. pushrods and 7/16 in. rocker studs
• Premium stainless steel intake and exhaust valves (with assembled heads)

Notes:
• As-cast bare heads require competition valve job and bowl blending
• Custom headers may be required for heads with raised exhaust port exits
• Check intake manifold for port match; not all intakes are compatible due to the tall high-flow ports (does not fit M-9424-Z51/-Z51P)
• Check piston-to-valve clearance, including radial valve clearance, before installing
