Air Flow Research AFR1132 Chev SB 302-350 V8 Eliminator Alloy Racing Heads Upgraded Springs

Get nasty with high-flowing AFR 235cc SBC Eliminator Competition Racing heads. These Competition package heads kick up your power production. Intake ports, exhaust ports, and cylinder heads are 100 percent CNC-ported with finer machine levels and improved port-shaped details for optimum flow characteristics. More flow plus higher velocity equals more torque and horsepower, and that adds up to a successful run for you. Proudly made in the USA, AFR Eliminator Competition heads will satisfy your big displacement small block Chevy engine's need for more air. And to achieve additional cooling in the center of the head, spread port styles are offered. Eliminator Competition heads come complete and ready to run with AFR power-proven components, or choose "bare" (no parts) heads to create your own personal power package!
