Description
A quality head gasket is the foundation of any reliable engine build—it’s the critical seal that keeps combustion pressures contained and prevents coolant crossover that can destroy your block. The Fel-Pro 400 Head Gasket with Steam Holes is purpose-built for small block Chevy engines, combining KEVLAR reinforcement with a steel core laminate to withstand the extreme pressures of high-performance applications. Whether you’re rebuilding a naturally aspirated stroker or a forced induction monster, this gasket delivers the durability and sealing integrity you need to run hard without worrying about failure.
