The SBC 305 Head Gasket from Mr. Gasket is a precision cylinder head gasket engineered for traditional GM small-block engines. This single-piece gasket is designed to seal the critical interface between the cylinder head and engine block, preventing coolant and oil leakage while maintaining combustion chamber integrity. Engine builders and enthusiasts rely on quality head gaskets like this to ensure reliable engine performance during both stock and modified applications.
The SBC 305 Head Gasket features a rubber-coated steel and graphite construction with a 3.870-inch bore diameter and 0.028-inch compression thickness, delivering the precise sealing required for traditional small-block architecture. The rubber coating provides conformability to ensure optimal contact across head and block surfaces, while the graphite and steel composition offers heat resistance and durability under sustained engine operation. Proper installation requires careful surface preparation of both the cylinder head and block deck to maximize gasket effectiveness and longevity.
This head gasket is ideal for engine builders, restoration shops, and small-block engine enthusiasts tackling cylinder head removal or complete engine assembly. Whether you're performing preventive maintenance or addressing a known leak, the SBC 305 Head Gasket is designed to meet the demands of high-performance applications.
