SBC 195cc Alum Heads Eliminator St 75cc

The SBC 195cc Alum Heads Eliminator St 75cc cylinder head pair represents a performance-focused upgrade for small block Chevrolet engines, engineered for street and mild competition builds. Originally designed for mechanics and engine builders seeking improved flow characteristics without sacrificing reliability, this aluminum head assembly delivers the breathing efficiency demanded by drivers who understand that cylinder head design directly impacts horsepower, throttle response, and overall drivability. Air Flow Research's Eliminator Street platform has earned respect in the engine building community for balancing aggressive intake flow with real-world street manners.

This assembled cylinder head features a 195 cubic centimeter intake runner volume paired with a 75 cubic centimeter combustion chamber, optimized for mid-range torque and responsive acceleration on pump gasoline. The 2.050-inch intake and 1.600-inch exhaust valves are sized to support increased airflow while maintaining port velocity characteristics essential for street applications, and the 1.290-inch valve springs provide consistent control under extended RPM operation. Aluminum construction keeps reciprocating mass low, reducing parasitic losses and improving engine efficiency compared to cast-iron alternatives, while angle plug design facilitates modern ignition system integration and promotes more uniform combustion patterns.

Engine builders and performance enthusiasts restoring or upgrading small block Chevy platforms benefit most from this head pairing, particularly those building 350 or 383 cubic inch combinations for street driving, autocross, or weekend track duty. The 75cc chamber is engineered to work with popular bore sizes and piston designs, allowing straightforward installation into existing engine blocks with standard bolt patterns and gasket surfaces. Proper cylinder head selection determines whether an engine achieves its intended performance envelope, and the Eliminator Street's reputation for delivering consistent gains in horsepower and fuel efficiency makes it a trusted choice for builders prioritizing both performance and reliability on the street.
