4.135 MLS Head Gasket .051 - SBC Brodix

The Cometic Gaskets 4.135 MLS Head Gasket .051 for SBC Brodix is a multi-layer steel cylinder head gasket engineered for small block Chevy engines equipped with Brodix performance heads. This precision component is designed to seal the combustion chamber under extreme compression loads while maintaining gasket integrity across extended operating temperatures—critical for both street performance and marine applications where consistent sealing prevents coolant leakage and compression loss.

The 0.051-inch compression thickness and 4.135-inch bore diameter are calibrated specifically for Brodix head geometry, ensuring proper combustion chamber volume and quench characteristics. Multi-layer steel construction provides superior sealing reliability compared to conventional single-layer gaskets, with the ability to handle elevated cylinder pressures typical of modified or turbocharged small block applications. The Cometic gasket's advanced coating technology resists corrosion from saltwater exposure and ethanol-blend fuels—essential considerations for marine engine rebuilds or freshwater performance builds operating in harsh environments.

This gasket suits engine rebuilders, marine technicians, and performance enthusiasts restoring or upgrading SBC-powered vessels and recreational equipment. Whether you're re-sealing a freshly bored block during a top-end rebuild or installing new Brodix heads as part of a performance upgrade, the correct head gasket thickness and bore diameter are non-negotiable for leak-free operation. Cometic's reputation for precision manufacturing and durability makes this gasket a trusted choice for applications where reliability matters and cost of failure is high.
