Speedmaster PCE281.1102.02 SBC 350 Aluminum Cylinder Head 160cc 64cc Angle Plug Semi-Finished

The Speedmaster PCE281.1102.02 is a high-performance bare aluminum cylinder head designed for small block Chevy 350 engines. This semi-finished head features a 23-degree valve angle with angled spark plug design, 160cc intake runners, and 64cc combustion chambers for optimal compression and flow characteristics.

Key Specifications:

• Combustion chamber volume: 64cc
• Intake port volume: 160cc
• Valve angle: 23 degrees
• Spark plug configuration: Angled
• Standard valve sizes: 2.020" intake, 1.60" exhaust (both +.100" length)
• Compatible with up to 2.05" intake valves with minimal machining
• Construction: Lightweight aluminum casting

Features & Benefits:

• CNC-machined combustion chambers, intake ports, and exhaust ports for consistent flow and performance
• Precision 4-axis and 5-axis CNC machining ensures exact chamber volumes and port-to-port consistency
• Superior control over flame travel and quench area compared to hand-ported heads
• Eliminates human error and variation found in traditional hand porting
• Each combustion chamber precisely matched for uniform compression ratio across all cylinders
• Bare head configuration allows custom valve train component selection

This semi-finished cylinder head is ideal for engine builders and performance enthusiasts who want CNC precision with the flexibility to finish assembly with their preferred valvetrain components. The angled spark plug design provides improved flame propagation and clearance in tight engine bay applications.
