SBC 210cc Alum Heads Eliminator Race 65cc A/P

The AIR FLOW RESEARCH SBC 210cc Aluminum Heads Eliminator Race 65cc A/P cylinder head is a purpose-built performance casting engineered for small block Chevy engines targeting serious competition and high-rpm applications. Supplied as a complete assembled pair, these heads deliver the flow characteristics and chamber geometry demanded by race shops and engine builders pursuing maximum horsepower from naturally aspirated or moderately boosted platforms.

The 210 cc intake port volume balances velocity and flow across the RPM band, while the compact 65 cc combustion chamber supports higher compression ratios without inducing detonation in pump gasoline. Intake and exhaust valve diameters of 2.080 and 1.600 inches respectively optimize the breathing envelope for Chevy small block configurations. The 1.550-inch valve springs provide appropriate preload and surge control for cam profiles in the 250–350 horsepower range. Angle-plug threading accommodates standard competition spark plugs and simplifies ignition system tuning. Aluminum construction keeps rotating assembly mass low, reducing parasitic loss and enabling faster acceleration response across mid and upper RPM ranges.

These heads suit engine builders preparing small block Chevy platforms for circle track, road course, or dyno testing where consistent flow metrics and proven casting integrity are non-negotiable. The Eliminator Race designation reflects AFR's focus on repeat-use, durable castings for teams running multiple event weekends or extended test sessions. Pair assembly simplifies installation scheduling and ensures matched flow characteristics between cylinder banks—critical for balanced EFI tuning and even cylinder temperature distribution at sustained high load.

AIR FLOW RESEARCH has established a reputation in the engine building community for precision port work and repeatable castings that perform predictably across many engine configurations. Buyers selecting this head should verify compatibility with their intended block, intake manifold, and cooling system before committing to purchase.
