Speedmaster Ford SB 289 302 351 Windsor 175cc 62cc Hydraulic Roller Assembled Cylinder Heads PCE281.2045

The Speedmaster Ford SB 175cc 62cc Hydraulic Roller Assembled Cylinder Heads (PCE281.2045) are precision-engineered performance heads designed for small-block Ford engines including 289, 302, and 351 Windsor variants. These fully assembled heads arrive ready to install, featuring a 175cc intake port volume and 62cc combustion chamber, optimized for improved airflow and combustion efficiency in street and mild performance applications.

The hydraulic roller design delivers reliable valve train operation and reduced maintenance compared to solid roller configurations, making these cylinder heads an excellent choice for builders seeking to upgrade breathing without extensive machine work. The 175cc port volume provides a balanced increase in volumetric efficiency suitable for naturally aspirated and moderately boosted engines, while the compact 62cc chamber promotes better flame travel and helps maintain pump gas compatibility. Installation is straightforward on compatible small-block Ford platforms, and the fully assembled construction eliminates the need for separate valve train components, saving time and ensuring factory-quality assembly standards.
