Cometic Jaguar 3.4L XK6 .059in CFM Cylinder Head Gasket - 85mm Bore

This Cometic CFM cylinder head gasket is built with a perforated-galvanized steel core, a solid choice for your Jaguar 3.4L XK6 engine. The asbestos-free fiber material applied to both sides helps ensure a good seal, which is critical for keeping combustion pressures contained and coolant and oil separate. It's designed with an 85mm bore and a .059 inch thickness, suitable for a range of classic Jaguar models from the early 1950s through the late 1960s.

The construction here is straightforward and effective. The galvanized steel core provides stability and strength, while the fiber material offers a compliant sealing surface. This combination is a well-known approach for creating durable head gaskets that can handle the pressures and temperatures found in an engine. It's a popular option for owners looking to rebuild or maintain their vintage Jaguar engines, ensuring proper compression and preventing leaks between critical engine components.
