The COMETIC GASKETS SBC MLS Head Gasket 4.125 Bore .036in is designed for small-block Chevrolet enthusiasts and professional engine builders who require reliable sealing in both high-performance and street applications. This multi-layer steel gasket effectively seals the critical junction between the cylinder head and block, where combustion pressures, coolant passages, and oil galleries converge.
With a thickness of .036 inches and a bore diameter of 4.125 inches, this gasket is engineered to fit standard small-block Chevrolet architecture while maintaining proper deck height and gasket crush specifications. The multi-layer steel (MLS) construction ensures a gas-tight seal under cylinder head bolt torque, providing durability and consistency to prevent leakage and maintain compression integrity.
Ideal for mechanics and engine shops, this gasket is suitable for various applications, including rebuilding classic engines or assembling stroker engines for sustained power delivery. Its design helps resist common failure points associated with inferior single-layer gaskets, making it a reliable choice for performance engines.
