Product Details

Cometic Gasket is known for making well-built sealing solutions for high-performance engines. This Multi-Layer Steel (MLS) head gasket is built for demanding applications like the Porsche 911, offering maximum sealing performance without needing extra sealants. It's designed to handle the high output these engines are known for.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and a 105mm bore, making it suitable for the left-hand side cylinders (1-3) on specific Porsche models.

This MLS design is ideal for sealing between aluminum heads and aluminum blocks, or aluminum heads and cast iron blocks, as it can manage the shearing forces that occur between dissimilar metals. It's a solid option for rebuilding the top end of your engine.
