SBC 190 Vortec Corona Series Cyl. Heads (Pair)

The SBC 190 Vortec Corona Series cylinder heads from Air Flow Research represent a precision-engineered solution for small-block Chevrolet enthusiasts seeking maximum flow efficiency without sacrificing reliability. These aluminum heads are purpose-built for builders who demand superior intake and exhaust flow characteristics while maintaining the iconic small-block platform's versatility. Whether you're building a street performance engine, a weekend warrior drag car, or a high-RPM road race application, this paired set delivers the respiratory upgrade your SBC needs to unlock hidden horsepower and improve throttle response across the RPM band.

Air Flow Research's Corona series design prioritizes flow optimization through carefully contoured intake and exhaust ports that minimize turbulence and maximize velocity. The 190cc intake runner volume strikes an ideal balance—large enough to support substantial airflow at higher RPMs, yet compact enough to maintain port velocity and fuel atomization for responsive low-end throttle feel. The Vortec casting platform integrates proven combustion chamber geometry with modern metallurgy, ensuring consistent performance across a wide range of operating conditions while resisting thermal stress common in modified engines. Weighing 66.6 lbs for the pair, these heads offer excellent strength-to-weight characteristics critical for performance applications where engine bay space and overall vehicle weight matter.

This cylinder head pair works best for builders stepping up from stock or basic performance heads and seeking a reliable foundation for carbureted or fuel-injected platforms up to naturally aspirated, supercharged, or turbocharged configurations. Installation requires proper gasket selection, accurate deck surface preparation, and attention to chamber volume matching for optimal combustion efficiency—standard practices any experienced small-block builder will recognize. The Vortec design maintains compatibility with common small-block accessories, allowing seamless integration into existing engine bays while preserving bolt-hole spacing and mounting provisions typical to the platform.
