4.060 MLS Head Gasket .027 - SBC

The 4.060 MLS Head Gasket .027 - SBC is a precision-engineered sealing solution designed specifically for Small Block Chevy engine platforms requiring a 4.060-inch bore diameter. Manufactured by Cometic Gaskets, this component is essential for engine builders and performance enthusiasts seeking to maintain optimal combustion chamber integrity under high-pressure conditions. Whether you are performing a standard rebuild or a high-output modification, this gasket ensures a reliable seal between the cylinder head and the engine block.

Utilizing advanced Multi-Layer Steel (MLS) technology, this gasket features multiple layers of stainless steel that provide enhanced rebound and structural durability compared to traditional composite materials. The 0.027-inch compression thickness is a critical specification for those looking to fine-tune their engine's quench distance and compression ratio. This thin profile allows for tighter tolerances, which can lead to improved thermal efficiency and more consistent performance across the power band.

Each 4.060 MLS Head Gasket .027 - SBC is designed to withstand the extreme thermal cycles and mechanical stresses common in performance-oriented Small Block Chevy applications. The outer layers are embossed and coated with a specialized material to provide a superior cold seal, while the inner shim layer provides the necessary support for high-clamping loads. This construction eliminates the need for retorquing and provides a more stable interface for both aluminum and cast-iron cylinder heads.
