SBC Parts Kit - (1) Head 2.02/1.60 1.250 Spring

The SBC Parts Kit featuring a cylinder head with 2.02/1.60 inch stainless valves and 1.250 inch springs is a comprehensive component assembly designed for small block Chevy engine builders and restoration specialists. This kit addresses the critical need for quality OEM-specification replacement parts when rebuilding or upgrading the cylinder head on classic and modern SBC platforms. Whether you're performing a complete engine refresh, addressing valve train wear, or building a performance-oriented small block, this DART-engineered parts kit provides the precision components necessary for reliable, long-term engine operation.

This SBC Parts Kit includes stainless steel valves sized at 2.02 inches for the intake and 1.60 inches for the exhaust, paired with 1.250 inch valve springs engineered to maintain consistent pressure across the RPM range. The complete assembly features valve retainers, locks, studs, guideplates, and seals—all critical components that work together to ensure proper valve sealing, guide alignment, and spring preload management. Stainless valve construction offers superior corrosion resistance and durability compared to standard steel, while the precision spring rate ensures optimal valve timing without flutter or float, even under high-load conditions. Each component is manufactured to exacting tolerances that support both stock and mildly modified small block Chevy applications.

Engine builders, restoration shops, and serious enthusiasts benefit most from this comprehensive parts kit, as it eliminates the need to source individual components separately while ensuring compatibility across the entire valve train assembly. Installation requires proper cylinder head preparation, valve seat work, and professional assembly techniques—tasks typically performed by experienced mechanics or machine shops familiar with small block Chevy head service. The kit's complete parts inventory makes it ideal for full cylinder head rebuilds, vintage engine restoration, or performance upgrades on any small block Chevy platform requiring factory-specification valve sizing and spring rates.
