How great is it that you can now do it at a price that's affordable. Our line of Big Block Ford performance heads have proven themselves time and time again both on the track and on the dyno, not to mention countless features in performance magazine articles. We offer Big block ford cylinder heads for a wide range of displacement applications. With bigger displacement engines becoming more common, the need for more airflow is necessary. If you are looking to build a 400-700 horsepower engine then you should consider Speedmaster Aluminum cylinder heads. Like the rest of our performance heads we use our "Gravity Die Cast“ process. This casting process creates a much more uniform and robust cylinder head. They also offer a smaller cross section to increase the incoming air"•s velocity resulting in improved drivability, power and economy. We have them available in as cast for the mild street applications and in Fully CNC machined for the serious enthusiast. Speedmaster CNC ported cylinder heads are machined on a dedicated 5 axis CNC machining centers to ensure accuracy and cost effectiveness. Combustion chamber, exhaust and intake ports are fully CNC machined for better flow. CNC combustion chambers offer superior control over flame travel and quench area. CNC ported heads eliminate human error and variation from port to port.  Intake & Exhaust GasketsOur Big Block Ford (385 Series) cylinder heads are designed to work with standard intake manifolds and exhaust headers.Recommended Intake Gaskets:Speedmaster PCE349.1009Fel-Pro #1231 (alternative)Recommended Exhaust Gaskets:Speedmaster PCE355.1009Fel-Pro #1420 (standard paper gasket)Head GasketsThese cylinder heads are compatible with standard OEM-style head gaskets.Recommended Head Gasket (Engines under 4.500" Bore):Fel-Pro #1018Head Bolts / StudsBig Block Ford engines utilize 9/16" diameter head bolts or studs.
