Speedmaster PCE281.1155 SBC 350 190cc Aluminum Cylinder Head 72cc CNC Chamber

The Speedmaster PCE281.1155 is a high-performance aluminum cylinder head designed for small block Chevy 350 engines. This bare cylinder head features advanced CNC porting and machining for superior airflow characteristics and consistent quality across every unit.

Key Specifications:

• 190cc intake runner volume for excellent mid-range power
• 72cc combustion chamber volume
• Angle plug design for improved flame travel and combustion efficiency
• CNC-machined chambers ensure identical port matching and flow characteristics
• Manufactured from lightweight aluminum alloy
• Bare head configuration (requires valve train components)

CNC Machining Advantage:

These cylinder heads are precision-machined on dedicated 5-axis CNC equipment, guaranteeing consistent port shapes, smooth surface finishes, and optimal flow characteristics that hand-porting cannot match. The CNC process eliminates variations between heads and ensures repeatable performance gains.

Ideal for street performance and mild racing applications on small block Chevy 350 builds. The 190cc runner volume provides strong torque and horsepower across the RPM range without sacrificing low-end response. Compatible with standard SBC valve train components and aftermarket performance parts.
