The Cometic GM LT1/LT4 Gen-II SB V8 .066in MLS Cyl Head Gasket-4.060in Bore-w/ Valve Pocketed Bores - C15520-066 is a precision-engineered head gasket with a 4.060" bore and .066" 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.
