Ford Racing 302/351W X2 Street Cruiser Assembled Aluminum Cylinder Head 64CC

This is the Ford Racing X2 Street Cruiser assembled aluminum cylinder head, designed for 289, 302, and 351 Windsor-style engines. It's a direct replacement for your stock heads, offering a significant horsepower boost for your street cruiser build. The 64cc combustion chamber volume is optimized for performance, working with the 188cc intake and 63cc exhaust ports to improve airflow.

Manufactured from high-quality 356-T6 aluminum castings, these heads are precision machined and assembled with premium components right here in the USA. They come complete with Ford Performance intake and exhaust valves, along with PAC 1219X Ovate Beehive valve springs, rated for camshaft lifts up to .600 inches. The design includes a wider valve cover gasket sealing rail to help prevent leaks and is machined for gasket seat spark plugs. Each aluminum head weighs about 25 lbs less than a comparable cast iron head, which can help with overall vehicle weight.

These heads are compatible with most Ford Performance and aftermarket hydraulic roller camshafts, as well as many intake manifolds, headers, and valve train components. You can use 1.6 or 1.7 ratio bolt-down rocker arms, but it's always a good idea to check rocker arm clearance to the valve springs. Depending on your lifter preload, you might need Ford Performance rocker shim kits. Each head is leak tested before assembly to ensure quality.
