This gasket features a 3.910-inch bore diameter and a compressed thickness of .054 inches, providing an optimal seal for both stock and performance builds.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 3.910-inch bore diameter accommodates standard LS bore sizes
• .054-inch compressed thickness for precise compression ratio tuning

Cometic's MLS gaskets feature multiple layers of stainless steel with proprietary coatings that provide excellent recovery and rebound characteristics. This design allows the gasket to maintain its seal integrity through thermal cycling and engine flexing, making it ideal for street performance, racing, and forced induction applications. The .054-inch thickness offers flexibility for builders looking to fine-tune compression ratios or accommodate slight deck height variations.
