The Speedmaster PCE281.1157 is a high-performance bare aluminum cylinder head designed for Small Block Chevy 350 engines. This precision-engineered head features 190cc intake runners and 68.5cc combustion chambers with an angled valve configuration for improved airflow and combustion efficiency.

Key Features:

• CNC-machined chambers on dedicated 5-axis CNC machines for exceptional accuracy and consistency
• 190cc intake runner volume optimized for street/strip performance
• 68.5cc combustion chambers allow for custom compression ratio tuning
• Angled valve design promotes better flow characteristics compared to straight plug heads
• Bare casting ready for final machine work and valve installation
• Durable aluminum construction for weight savings and heat dissipation

These CNC ported cylinder heads deliver superior flow characteristics compared to stock castings, making them an excellent choice for performance builds. The bare head design allows engine builders to customize valve sizes, spring packages, and final chamber volumes to match specific compression and performance goals.
