About this part

Product Details

If you're rebuilding the top end of your Nissan KA24DE engine, or working on a Jaguar XK series from the 50s, a solid head gasket is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines and a variety of engine builds.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals well against aluminum or cast iron blocks and heads, even with different materials. This design means you don't need to add any sealants. The center layer is stainless steel and can be varied in thickness to achieve different compression ratios; this particular gasket has a compressed thickness of .089 inches and a 90mm bore, making it suitable for engines with those specifications.

This gasket is a well-built option for many applications, including the Nissan 240SX, Frontier, and Xterra, as well as older Jaguar XK models. It's designed to provide reliable sealing for your engine rebuild.
