Michigan Motorsports MLS Head Gasket Pair for 6.0L & 6.2L LS Engines — Stainless Multi‑Layer, Boost‑Ready Seal

BTR Brian Tooley Racing MLS head gasket pair provides multi-layer stainless steel sealing engineered for 6.0L and 6.2L LS rectangle-port engines, delivering durable, leak-resistant performance for stock rebuilds and high-power builds.

These matched head gaskets from Brian Tooley Racing are built to withstand elevated cylinder pressures and frequent thermal cycles common in modern LS swap, stroker, and boosted applications. Designed for compatibility with a wide range of Gen III/IV rectangle-port engines (including L99, L76, L77, LS2, L92, L96, L94, L9H, LQ4, and LQ9), the MLS construction balances clamping strength, longevity, and consistent combustion sealing so your top end stays reliable under stress.

How do these gaskets handle high boost and elevated cylinder pressures?

BTR MLS gaskets use multiple stainless steel layers that resist blowout and retain a tight seal as cylinder pressure rises. The layered construction conforms to flange surfaces while resisting permanent deformation, giving confident sealing in boosted or high-compression engines.

• Multi-layer steel resists extrusion and blowout under boost.
• Precision bore and sealing beads for consistent combustion control.
• Engineered to maintain clamp load across thermal cycles.

Will these gaskets fit my LS3, LS2, or truck-based LS engine?

Yes — this set is made for LS rectangle-port 6.0L and 6.2L cylinder heads and fits a wide list of factory codes. Sold as a matched pair, the gaskets are sized to replace stock units while offering a performance-oriented sealing upgrade for many Gen III/IV platforms.

• Compatible with L99, L76, L77, LS2, L92, L96, L94, L9H, LQ4, LQ9.
• Designed for both passenger-car and truck-based LS variants.
• Supplies two gaskets for complete cylinder head replacement.

What installation considerations should builders know?

MLS gaskets require clean, flat mating surfaces and correct head-bolt torque sequence to perform as intended. Follow manufacturer torque specs and use new fasteners if recommended; proper surface prep and torque prevent leaks and ensure the MLS stack compresses evenly.

• Machine or thoroughly clean head and block surfaces before installation.
• Use the correct torque sequence and values for your engine variant.
• Replace head bolts if torque-to-yield fasteners are specified by the engine builder.

How do BTR MLS gaskets compare to stock replacements?

Compared with many OEM composite gaskets, BTR MLS units offer superior resistance to combustion leakage and improved durability at higher power levels. They are intended to be a direct-fit, long-lasting replacement that also supports performance modifications without sacrificing reliability when installed correctly.

• Better thermal stability and clamp retention than many OEM materials.
• Direct-fit for rectangle-port LS heads—no modification required.
• Proven in street and strip environments by experienced LS builders.

Who is this for: Engine builders, enthusiasts, and professional shops refreshing or upgrading LS 6.0L/6.2L top ends who need dependable combustion sealing under elevated RPM, boost, or compression. Whether you’re restoring a daily driver, assembling a cammed weekend car, or building a high-horsepower forced-induction engine, the BTR MLS head gasket pair offers a robust, bolt-on sealing solution that supports aggressive performance goals while maintaining fitment and serviceability.
