4.080 MLS Head Gasket .040 - SBF SVO

The 4.080 MLS Head Gasket .040 for Small Block Ford SVO is a precision-engineered sealing solution designed for serious engine builders and high-performance enthusiasts rebuilding or modifying classic and modern Small Block Ford engines. This Multi-Layer Steel gasket represents the evolution of head gasket technology beyond traditional single-layer designs, offering superior durability and reliable compression sealing in demanding applications. Whether you're restoring a vintage Windsor engine or upgrading a performance SVO platform, this gasket delivers the sealing integrity required for sustained horsepower and cylinder pressure control.

Built by Cometic Gaskets—a leader in premium gasket manufacturing—the 4.080 MLS design uses multiple steel layers bonded with elastomer to prevent gasket failure under high combustion pressures and thermal cycling. The .040-inch thickness is calibrated for standard SVO deck heights and maintains consistent crush pressure across the sealing surface without over-compression of cylinder liners. The 4.080-inch bore diameter accommodates typical Small Block Ford stroke combinations, ensuring proper clamping force distribution and a tight, long-lasting seal between block and cylinder head.

This gasket is ideal for engine rebuilds, stroker conversions, naturally aspirated performance builds, and mild forced-induction setups where reliable sealing matters. Mechanics and engine shops consistently specify MLS gaskets for rebuild jobs because they resist blow-out and deformation better than composite designs, reducing comebacks and warranty claims. Always verify deck height and head bolt torque specifications for your specific block and cylinder head combination before installation to ensure optimal clamping load and gasket performance.
