The Cometic Jaguar 3.4L XK6 .086in MLS Cylinder Head Gasket - 85mm Bore - C4303-086 is a precision-engineered head gasket with a 85mm bore and .086" compressed thickness.

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.
