AFR 210cc/ 75cc Race Cylinder Head SBC

Higher RPM Small Block Chevy race engines require increased airflow and valvetrain stability. This cylinder head supports competition builds operating between 6,500 and 6,800 RPM. Fully CNC-ported intake runners, exhaust runners, and combustion chambers provide consistent airflow characteristics without additional machine work. Cast from A356 aluminum, the cylinder head combines strength with effective heat control.
