Cometic Porsche 928 83-97 104mm Bore .051 inch MLS Head Gasket Left Side H/G

If you're rebuilding the top end of your 1985-1995 Porsche 928, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option for the left side. It's built with multiple layers of stainless steel, which gives it the strength to handle the forces involved in high-output engines and helps prevent corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and works well with different head and block materials, whether you have aluminum heads on an aluminum block or aluminum heads on cast iron. This gasket has a compressed thickness of 0.051 inches and is designed for a 104mm bore, meaning it seals precisely where it needs to without requiring any additional sealants.

The multi-layer steel construction is key here. It allows the gasket to rebound and resist the shearing forces that can occur when different metals are used for the heads and the block. This design makes it a good choice for both aluminum-to-aluminum and aluminum-to-iron setups. The Viton coating on the embossed outer layers is rated for temperatures up to 482 degrees Fahrenheit, ensuring it holds up under demanding conditions. The center layer is stainless steel and can be varied to achieve different thicknesses, but this specific gasket is set at 0.051 inches compressed thickness for a precise fit.
