4.135 MLS Head Gasket .051 - SBC Brodix

The Cometic Gaskets 4.135 MLS Head Gasket .051 for SBC Brodix cylinder heads is designed for serious small-block Chevy builders and engine enthusiasts who require reliable sealing under high compression and boost conditions. This multi-layer steel (MLS) gasket represents the modern standard for performance engine assembly, replacing traditional cork and composite designs that often fail under sustained power output.

The .051-inch thickness of this MLS head gasket is precisely engineered to accommodate Brodix cylinder head geometry and compression ratios typical in performance applications. Its multi-layer steel construction utilizes alternating layers of spring steel and elastomer to maintain consistent clamp load across the gasket face, preventing hot-spot blowouts and cylinder-to-cylinder leakage even under elevated boost or nitrous conditions.

This gasket is ideal for engine builders and mechanics assembling small-block Chevy engines with Brodix aluminum or iron cylinder heads, ensuring perfect alignment with cylinder walls and fire rings that isolate combustion pressure from coolant passages. Cometic's manufacturing tolerances guarantee uniform thickness and proper surface finish compatibility with modern cylinder heads and blocks, making it a reliable choice for street machines, bracket racing engines, or forced-induction small-blocks.
