Cometic Jaguar 3.4L XK6 .027in MLS Cylinder Head Gasket - 85mm Bore

When you're rebuilding the top end of your classic Jaguar, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built with the 3.4L XK6 engine in mind, featuring an 85mm bore and a compressed thickness of 0.027 inches. It's designed to handle the pressures of higher output engines, ensuring a reliable seal without needing extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance, which also helps them rebound and maintain their seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, making it suitable for aluminum heads on either aluminum or cast iron blocks. The center layer is uncoated stainless steel, allowing for precise thickness control.

This gasket is a well-built option for your 1951-1957 Jaguar Mark VII, 1957-1958 Mark VIII, 1949-1953 XK120, 1955-1957 XK140, or 1958-1961 XK150. Ensure you consult your service manual for the correct installation procedures and any required hardware.
