SBC 230cc Pro-1 Head 64cc A/P 2.08/1.60 Bare

The SBC 230cc Pro-1 Head 64cc A/P 2.08/1.60 Bare from DART is purpose-built for serious small-block Chevy engine builders seeking maximum flow potential without compromise. This bare cylinder head is engineered for high-performance street and competition applications where improved breathing directly translates to power gains. Whether you're building a naturally aspirated stroker or preparing a platform for forced induction, this DART casting delivers the foundation needed to unlock your engine's full potential.

The 230cc intake and exhaust port volumes represent a significant step up from factory small-block heads, enabling superior volumetric efficiency across the RPM band. The 64cc combustion chamber is optimized for quench and flame propagation, while the 2.08-inch intake valve and 1.60-inch exhaust valve configuration balances flow characteristics with structural durability. As a bare casting, this head arrives without valve train components, rocker studs, or installed valves—giving you complete control over your final assembly specifications and allowing selection of valve diameters, springs, and components tailored to your exact build requirements.

This head is ideal for engine builders who demand precision and versatility in their SBC platform. The larger port sizing suits applications ranging from 383 to 427+ cubic inch displacements, making it compatible with both conventional and modern fuel-injection setups. Installation requires proper surface preparation, gasket selection matched to your block and head gasket thickness, and attention to valve clearance specifications during final assembly. Weight at 22.6 pounds reflects the robust casting construction necessary for sustained high-rpm operation and boost-capable platforms.
