Pro Copper LH Head Gskt 4.160 X .062 LS/LSX/LS7

The Pro Copper LH Head Gasket 4.160 X .062 for LS/LSX/LS7 engines is purpose-built for serious LS platform builders and mechanics who demand reliability under extreme combustion pressures. Whether you're assembling a street performance engine, a race-prepped block, or rebuilding after a head gasket failure, this left-side gasket delivers the sealing integrity required for forced induction, high-boost, and naturally aspirated applications. The 4.160-inch bore diameter matches Gen III and Gen IV LS head specifications, making it essential inventory for any shop specializing in LS engine work.

SCE Gaskets' copper construction with a .062-inch compressed thickness provides superior heat transfer and thermal cycling resistance compared to standard steel gaskets. Copper's excellent conductivity helps dissipate combustion heat away from the combustion chamber, reducing hot spots that can lead to detonation and gasket failure. The precise 4.160-inch bore and engineering tolerances ensure consistent compression and eliminate micro-leaks that plague inferior gaskets on high-horsepower builds. This composition is specifically formized to handle the demanding 11.0:1 compression ratios and aggressive timing curves common in LS7 and boosted LSX platforms.

Mechanics and engine builders targeting 500+ horsepower applications will appreciate the reliability and longevity this gasket provides over the engine's service life. Installation is straightforward on LS platforms—the left-hand gasket pairs with its right-side counterpart using standard GM head bolt torque specs. Whether you're replacing a failed OEM gasket or upgrading during a complete rebuild, the Pro Copper LH Head Gasket ensures a proper seal without the guesswork. Compatible with all LS, LSX, and LS7 variants, this gasket is a critical foundation for any engine that demands maximum reliability and performance.
