SBC LT1 195cc Alum Heads Eliminator Street A/P

The SBC LT1 195cc Alum Heads Eliminator Street A/P cylinder head is designed for Gen 1 small-block Chevy LT-series engine builders and restoration professionals. This product, engineered by Air Flow Research, addresses the needs of street performance and marine markets by maximizing flow efficiency while ensuring drivability and reliability on pump gasoline.

Built for 1992–1997 GM LT1 applications, this aluminum casting provides the necessary thermal management and port velocity characteristics for sustained power delivery in high-heat environments. Each head features a 195 cc intake port and a 65 cc combustion chamber, balancing cylinder filling with quench and detonation control. The 2.050-inch intake and 1.600-inch exhaust valve package, along with 1.290-inch valve springs and angle-plug configuration, optimizes spark timing geometry and spring preload consistency.

Street enthusiasts, classic Corvette and Camaro owners, and engine builders will benefit from this design philosophy that prioritizes throttle response, part-throttle efficiency, and long-term reliability over peak-RPM numbers. The assembled condition means springs, valves, and hardware are pre-installed and torque-checked, ensuring factory-correct geometry and eliminating assembly labor.
