      The Best Cylinder Head for Your Needs. The Ford Performance 302/351W Z-Head 63-cc Aluminum Cylinder Head With 7mm Valves is the ideal cylinder head for your 302 or 351 Windsor engine-equipped Mustang. This assembled cylinder head is designed to provide optimized airflow and improved combustion via a number of innovative features. The result is increased power and torque, giving you the performance edge on the track.

      Advanced Performance. The Ford Performance 302/351W Z-Head 63-cc Aluminum Cylinder Head with 7mm Valves features a fully CNC-machined 63-cc combustion chamber producing more efficient combustion, as well as reduced carbon build-up. This cylinder head uses 7mm stemmed 2.02-inch intake and 1.60-inch exhaust valves providing improved airflow. Additionally, this aluminum cylinder comes built-in with high-flow ports, maximizing airflow even further.

      Beefed-Up Construction. The Ford Performance 302/351W Z-Head 63-cc Aluminum Cylinder Head with 7mm Valves is manufactured from cast A356 T6 aluminum for superior strength-to-weight ratio. This cylinder head weighs 27 pounds, making it much lighter than stock. The intake and exhaust valves are constructed from stainless steel and utilize manganese-bronze guides for smooth operation. Also, this cylinder head comes pre-installed with steel alloy valve seats for an effective seal.

      Direct Bolt-On Installation. The Ford Performance 302/351W Z-Head 63-cc Aluminum Cylinder Head With 7mm Valves is designed to bolt-on directly to your 302 or 351 Windsor engines. The installation will need expert-level mechanical knowledge and skills, as well as a complete set of tools. You will also need a full day’s work. As such, professional installation is highly recommended.

      Application. The Ford Performance 302/351W Z-Head 63-Cc Aluminum Cylinder Head With 7mm Valves fits 302 And 351 Windsor-Style Engines.

      Application Notes. The Ford Performance 63-cc Aluminum Cylinder Head With 7mm Valves is intended for competition use only, and should not be installed on a vehicle that will be driven on public highways and roads. This cylinder head will require roller rocker arms with a 1.65:1 or 1.5:1 ratio, and a 0.150-inch offset intake pushrod cup. Additionally, custom headers and a raised exhaust port exit may also be required.

        Great heads for the price

        Easy to install took me an afternoon. Everything matched up, very good product for the price. I’m not a skilled mechanic but it was so easy a 3rd grader could put it together

      if the rocker roller arms need off set on intake will the ezhaust need the same or will the stock roller arms work for ezhaust? where can i get the off set rocker roller arms for intake?

      • For those kinds of builds, we recommend checking out forums or consulting with a performance shop, they will give a much more detailed list of the parts that you will need, and might also have links to pre-configured kits as well.
