SBC 165cc I/E Head 76cc 1.94/1.50 Bare

The SBC 165cc I/E Head 76cc 1.94/1.50 Bare from DART is designed for serious small-block Chevrolet engine builders who prioritize maximum flow efficiency and cylinder head performance. This bare casting serves as a significant upgrade over stock components, engineered for street, strip, and competition applications where intake and exhaust flow characteristics are crucial for horsepower and torque delivery.

With a 165cc intake port volume optimized for SBC applications, this cylinder head is ideal for builders looking to enhance scavenging efficiency across a broad RPM range. The 76cc combustion chamber volume and 1.94-inch intake / 1.50-inch exhaust valve sizes create excellent flow dynamics while maintaining appropriate compression ratios for various fuel octane ratings and boost applications. As a bare casting, it is ready for porting, valve seat installation, and custom machine work, allowing builders to tailor specifications to their exact engine combination and performance goals.

This cylinder head is particularly beneficial for experienced engine builders and machine shops, providing a solid foundation for reliable, repeatable power gains. The substantial weight of 47.34 lbs reflects quality casting integrity and material density, ensuring resistance to thermal warping under sustained high-load conditions. Whether building a mild stroker or preparing a high-RPM engine platform, this head meets the needs of various performance enthusiasts.
