SBC 235cc CNC Alum Heads Eliminator Race 70cc A/P

The SBC 235cc CNC Alum Heads Eliminator Race 70cc A/P cylinder head pair from Air Flow Research is designed for serious small-block Chevy performance builds, where every cubic centimeter of displacement and airflow velocity is crucial. These assembled aluminum heads are tailored for racers and high-horsepower enthusiasts who seek maximum intake and exhaust efficiency without compromise. Whether you are constructing a street-strip hybrid or a dedicated circle-track engine, this cylinder head set lays the groundwork for reliable high-RPM performance.

These CNC-ported aluminum heads feature 235 cubic centimeter intake runners and a compact 70 cubic centimeter combustion chamber, a proven combination that enhances fuel atomization and flame propagation across the RPM range. The heads are equipped with 2.100-inch intake valves and 1.600-inch exhaust valves to optimize breathing capability. The angle-plug configuration ensures optimal spark positioning for efficient combustion, while the fully assembled design minimizes assembly variables that could compromise performance or reliability.

Small-block Chevy racers, from 406ci strokers to naturally aspirated displacement engines, depend on these heads for consistent performance in the mid-5000 to 7000 RPM range during bracket racing, heads-up competition, and engine dyno validation. This product is compatible with small block Chevy platforms and is ready to install right out of the box, making it an excellent choice for those looking to enhance their engine's performance.
