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 PCE281.1654 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 CNC Ported PCE281.1656 heads. The mid-size cross section works well on larger displacement engines and in and under 7000RPM. If you re looking for more horsepower the PCE281.1658 with their competition valve job fit the bill perfectly. HEAD GASKETS Due to t
