The Cometic Ford Y-Block Top End Gasket Kit - 3.940in Bore - .030in MLS Cylinder Head Gasket - PRO1039T-3940-030 is a precision-engineered head gasket with a 3.940" bore and .940" compressed thickness.
The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
