4.165 MLS Head Gasket .027 - SBC

The 4.165 MLS Head Gasket .027 - SBC from Cometic Gaskets is designed specifically for small-block Chevrolet engines, providing a reliable seal at the cylinder head interface. This gasket is essential for both street and performance applications, where maintaining optimal combustion chamber sealing is critical to engine performance. Builders and engine shops will appreciate its durability and precision engineering.

Constructed from multi-layer steel (MLS), this gasket features precisely stamped stainless steel layers bonded with elastomer, ensuring even distribution of clamping load across the head deck. This design minimizes the risk of soft-spot failures that are common with single-layer gaskets. The .027-inch compressed thickness is specifically calibrated for small-block Chevrolet head geometry, allowing for correct combustion chamber volume and piston-to-valve clearance.

This gasket is particularly beneficial for high-performance builds, including turbocharged and supercharged applications, where traditional gaskets may fail under extreme conditions. It is compatible with various small-block Chevrolet engine displacements, including 262, 283, 305, 327, 350, and 400 CID, making it a versatile choice for engine builders.
