AFR 227cc SBC Eliminator Race Ready Racing Heads
AFR 227cc SBC Eliminator Race Ready Racing heads offer outstanding track performance at a competitive price. Exhaust and intake ports and combustion chambers are 100 percent CNC-ported, with coarser machine levels for terrific flow characteristics and big power gains.
The 227cc SBC Eliminator heads feature a 3/4 in. thick head deck, ideal for nitrous or blower applications. They come complete and ready-to-run with quality AFR-proven components for maximum reliability—or choose "bare" heads (no parts) to design your own ultimate power package. These cylinder heads are available in standard and spread port exhausts. AFR 227cc SBC Eliminator Race Ready racing heads are a great choice for budget-minded racers.
