What does 'bare' mean for these cylinder heads?

A 'bare' cylinder head means it comes without valves, springs, retainers, or other valvetrain components. You will need to purchase these separately and have a competition valve job and bowl blending performed before installation.

Will I need new headers for these heads?

The Z-Heads feature a raised exhaust port exit. This design often requires custom headers to ensure proper fitment and exhaust flow, so it's recommended to plan for this possibility.

Are these heads street legal in California?

No, these heads are not CARB approved and cannot be legally shipped to California due to emissions regulations.

Product Details

This is a bare set of Ford Racing Z-Heads, specifically designed for 302 and 351W Windsor engines. These heads are cast from prime A356 T6 aluminum, a material chosen for its strength and lighter weight compared to iron. They were developed using advanced solid modeling technology to optimize airflow and performance for a wide range of Ford vehicles, including models like the Ford Bronco, Ford E-Series vans, and the De Tomaso Pantera.

The Z-Heads feature high-flow ports that have been CNC-machined in the combustion chambers to a precise 63cc volume. They come with manganese-bronze valve guides installed with a semi-finished ID, ready for a competition valve job and bowl blending. Steel alloy intake and exhaust valve seats are also pre-installed, and the heads accept both tapered seat and gasket-style 14mm spark plugs. The raised exhaust port exit means you might need custom headers to match, but this design contributes to the overall improved flow characteristics.

Because these are bare heads, they require a competition valve job and bowl blending to be fully prepared for installation. This allows you to customize the setup precisely to your engine's needs. They are made in the USA and represent a solid option for anyone looking to significantly upgrade their Windsor engine's breathing capabilities.
