The Cometic GM LM7/LQ4 Vortec Small Block V8 Top End Gasket Kit-4.020in Bore-.051in MLS Cyl Head Gasket - PRO1008T-051-4020 is a precision-engineered head gasket with a 4.020" bore and .020" 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.
