SBC 190 Vortec Corona Series Cyl. Heads (Pair)

The SBC 190 Vortec Corona Series cylinder heads from Air Flow Research are designed for small-block Chevrolet enthusiasts who seek enhanced flow efficiency and performance. These aluminum heads cater to builders looking for superior intake and exhaust flow characteristics, making them ideal for street performance engines, drag cars, or high-RPM road race applications.

The design of the Corona series prioritizes flow optimization through carefully contoured intake and exhaust ports, which minimize turbulence and maximize velocity. With a 190cc intake runner volume, these heads strike a balance between substantial airflow at higher RPMs and maintaining port velocity for responsive low-end throttle feel. The construction utilizes advanced aluminum casting techniques to ensure durability and performance consistency.

These cylinder heads are particularly beneficial for builders aiming to unlock hidden horsepower and improve throttle response across the RPM range. Weighing 66.6 lbs for the pair, they offer excellent strength-to-weight characteristics, making them suitable for performance applications where engine bay space and overall vehicle weight are critical considerations.
