Speedmaster Chevy 454 360cc Angle Plug Aluminum Bare Cylinder Head

As with all Speedmaster cylinder heads, our Big Block Chevrolet heads are "Gravity Die Cast". This casting process creates a much more uniform and robust cylinder head. With the increasingly large displacements becoming common, the need for more airflow is necessary. If you are looking to build a 400-500+hp engine, give our PCE281.1489 heads a try. They offer a smaller cross - section to increase the incoming air"s velocity, resulting in great driveability, power and economy. On engines over 500hp, use the rectangle port PCE281.1488 heads. The mid-size cross section works well on engines under 540cu.in and under 7000RPM. If you are working on a larger, or higher RPM engine, step up to PCE281.1510 or the CNC ported PCE281.1511 heads. The added volume of the PCE281.1511 intake ports (360cc) helps to fill in the gap between As-Cast performance heads and All-Out racing heads. If you"re looking for 750+hp the PCE281.1523 with their competition valve job fit the bill perfectly. | Brand:Speedmaster
