SBC LT1 195cc Alum Heads Eliminator Street A/P

The SBC LT1 195cc Alum Heads Eliminator Street A/P cylinder head represents a proven solution for Gen 1 small-block Chevy LT-series engine builders and restoration professionals. Engineered by Air Flow Research, this assembled pair addresses the core demand in the street performance and marine markets: maximizing flow efficiency without compromising drivability or reliability on pump gasoline. Built for 1992–1997 GM LT1 applications, this aluminum casting delivers the thermal management and port velocity characteristics required for sustained power delivery in high-heat environments typical of daily-driven and weekend warrior builds.

Each head features a 195 cubic-centimeter intake port and a 65 cubic-centimeter combustion chamber, sized to balance cylinder filling with quench and detonation control. The 2.050-inch intake and 1.600-inch exhaust valve package, paired with 1.290-inch valve springs and angle-plug configuration, optimizes spark timing geometry and spring preload consistency. Aluminum construction reduces parasitic weight while maintaining the structural rigidity necessary for sustained RPM loads; the assembled condition means springs, valves, and hardware are pre-installed and torque-checked, eliminating assembly labor and ensuring factory-correct geometry. This design philosophy prioritizes street usability—throttle response, part-throttle efficiency, and long-term reliability—over peak-RPM numbers.

Street enthusiasts, classic Corvette and Camaro owners, and engine builders seeking a bolt-on upgrade for naturally aspirated LT1 engines will find this pair a direct bolt-in replacement that requires no manifold or intake modification. Compatibility is confirmed for 1992–1997 Chevrolet LT1-block vehicles; verification of compression ratio and fuel octane requirements is recommended prior to installation. Weighing 63 pounds per pair, these heads are suitable for fuel-injection and carbureted applications, making them a flexible choice for both resto-mod and performance-street builds. Installation follows OEM torque specifications and standard cylinder-head gasket procedures.
