The SBC 230cc Pro-1 Head 64cc A/P 2.08/1.60 Assembly from DART is designed for small-block Chevrolet enthusiasts who prioritize performance and reliability. This assembly is ideal for street performance, mild turbocharged applications, and naturally aspirated builds, where enhanced airflow can lead to significant horsepower gains. It simplifies the process of selecting compatible valve sizes and chamber volumes, making it a great choice for both seasoned builders and newcomers.

Featuring a 230cc intake port volume, this head assembly provides superior flow characteristics across the RPM range, resulting in improved volumetric efficiency compared to factory castings. The 64cc combustion chamber is optimized for compression ratios between 9.5:1 and 11:1, depending on the piston selection, effectively balancing power output and detonation resistance. The valve sizes of 2.08 inches for intake and 1.60 inches for exhaust maximize scavenging and fuel charge velocity while ensuring durability.

This head assembly is perfect for builders aiming for 350–400 hp in naturally aspirated setups or those venturing into entry-level forced induction platforms. DART's commitment to quality ensures consistent port matching and proper valve seat angles, eliminating the need for extensive porting work. With this assembly, builders can expect a reliable and efficient performance upgrade for their small-block Chevrolet engines.
