Premium MLS Sealing for GM Gen IV LS Engines
Whether you're performing a factory replacement, rebuilding a daily driver, or assembling a high-performance street, racing, towing, or forced-induction LS engine, dependable cylinder head sealing is essential. TSP MLS Cylinder Head Gaskets feature multiple embossed stainless steel layers with a rubber sealing coating to withstand elevated cylinder pressures while helping prevent combustion, coolant, and oil leaks under demanding operating conditions.

Precision Fit for Popular Gen IV LS Applications
Manufactured as a direct replacement for GM part number 12610046, these cylinder head gaskets feature a 4.080-inch bore and 0.051-inch compressed thickness for precise sealing and consistent compression characteristics. They are compatible with LS2, LS3, L76, L77, L92, L94, L96, L99, L9H, LY6, and LC8 Gen IV LS engine applications.

Engineered for Street, Performance, and Racing Builds
Multi-layer steel (MLS) construction provides outstanding durability for naturally aspirated, nitrous oxide, supercharged, and turbocharged engines when installed on properly prepared block and cylinder head surfaces. Sold as a matched pair, these head gaskets deliver dependable sealing performance for stock replacement engines and high-horsepower LS builds alike.

Which engines do these head gaskets fit?
These head gaskets are designed for GM Gen IV LS engines using a 4.080-inch bore, including the LS2 (6.0L), LS3 (6.2L), and L92 (6.2L). Always verify your engine code, bore size, and required gasket thickness before installation.

Are these MLS head gaskets?
Yes. They feature a multi-layer steel (MLS) construction with a rubber sealing coating for superior combustion, coolant, and oil sealing compared to conventional composite head gaskets.

Are these sold individually or as a pair?
They are sold as a matched pair, providing both left- and right-side cylinder head gaskets for one complete V8 engine.

What is the compressed thickness?
These head gaskets have a compressed thickness of 0.051 inch.

What is the bore size?
Each head gasket features a 4.080-inch (103.632 mm) bore diameter.

Can these be used on turbocharged or supercharged engines?
Yes. MLS head gaskets are commonly used in naturally aspirated, turbocharged, supercharged, and nitrous-assisted LS engine builds when proper block and cylinder head surface finishes are maintained.

Do I need to use additional gasket sealant?
No. MLS head gaskets are designed to be installed dry unless otherwise specified by your engine builder or the factory service manual.

Can these be reused?
No. Like all MLS head gaskets, they should be replaced whenever the cylinder heads are removed to ensure a proper seal during reassembly.
