LS Titan Copper LH Head Gasket 4.160 X .043

The LS Titan Copper Head Gasket 4.160 X .043 from SCE Gaskets is engineered for serious LS engine builders and high-performance mechanics who demand reliability under extreme combustion pressures. This head gasket is purpose-built for LS platform engines—the workhorse of modern performance builds—where factory gaskets often fail under boosted, nitrous, or high-compression applications. Whether you're rebuilding an LS1, LS2, LS3, or LSX variant, a quality head gasket is essential; poor sealing can lead to coolant weeping, oil migration, and catastrophic head lift during peak boost or cylinder pressure spikes.

SCE's Titan Copper construction features a multi-layer steel core with pure copper facing on both sides, a proven design that handles thermal cycling and mechanical stress better than conventional composite gaskets. The 4.160-inch bore diameter matches LS platform cylinder head castings precisely, while the 0.043-inch thickness is calibrated to maintain proper compression ratios and valve-to-piston clearance—critical when running custom pistons or high-lift camshafts. This design also accommodates thermal expansion differentials between aluminum heads and cast-iron blocks without degradation.

Mechanics and engine builders trust SCE Titan Copper gaskets for naturally aspirated, turbocharged, and supercharged applications. The superior gas seal resists blow-by even at 12+ psi of boost or elevated compression ratios above 11:1, making it an ideal choice for high-performance builds. With its reliable construction, this gasket is a crucial component for anyone looking to maximize the performance and durability of their LS engine.
