4.160 MLS Head Gasket .040 - SBC Brodix

The Cometic Gaskets 4.160 MLS Head Gasket .040 - SBC Brodix is a precision cylinder head gasket engineered for small block Chevy engines equipped with Brodix performance heads. Built for anglers and boaters who demand reliability on the water, this multi-layer steel gasket seals critical combustion chamber interfaces where high RPM operation and thermal cycling can compromise engine integrity. Whether you're maintaining a freshly rebuilt marine powerplant or upgrading an existing engine platform, this gasket represents the seal quality necessary to prevent compression loss and coolant seepage.

Cometic's multi-layer steel construction provides superior gasket crush resistance and thermal stability compared to traditional composite designs, critical attributes for marine applications where engine compartments experience elevated ambient temperatures and prolonged full-throttle operation. The .040-inch compression thickness is precisely calculated for the Brodix head casting geometry, ensuring optimal bore sealing with the 4.160-inch bore diameter while maintaining proper valve train geometry and combustion chamber volume. This gasket's composition prevents blowout under sustained high boost conditions and maintains its seal integrity across repeated thermal expansion cycles—essential when transitioning between cool morning water and full-sun performance runs.

Marine engine builders and experienced weekend racers standardize on Cometic gaskets for small block Chevy restorations and performance upgrades because the brand's engineering eliminates guesswork during reassembly. This gasket is specifically designed for Brodix head applications and must be paired with compatible cylinder head and block surfaces; verify your head casting matches Brodix specifications before ordering. Installation requires standard torque procedures and appropriate head gasket sealant per engine builder recommendations. For boaters running carbureted or fuel-injected small block platforms, this gasket ensures thousands of reliable hours whether cruising coastal waters or competing in marine racing series.
