Cometic C9793-040 Millennium Head & Base Gasket Kit 3-13/16" Bore .040" Head .020" Base

The Cometic C9793-040 Millennium Head and Base Gasket Kit delivers professional-grade sealing for 3-13/16" bore engines. This complete kit includes a .040" thick Multi-Layer Steel (MLS) head gasket and a .020" thick base gasket, engineered to provide reliable sealing under extreme pressure and temperature conditions.

Key Features:

• Multi-Layer Steel (MLS) head gasket construction with .040" thickness for superior combustion sealing
• .020" thick base gasket included for complete cylinder sealing solution
• Designed for 3-13/16" bore applications
• Proprietary high-temperature coatings and embossments create micro-seals against head and block surfaces
• Fluoroelastomer (Viton) coating on steel layers for enhanced chemical and heat resistance
• Made in the USA with American-sourced materials

Cometic's Millennium series gaskets feature advanced multi-layer technology where thin, coated spring steel outer layers enclose an inner steel core. This design allows the gasket to adapt to surface imperfections while maintaining consistent clamping force across the sealing surface. The MLS construction provides active combustion sealing on multiple layers, preventing the mixing of gases and fluids while withstanding the demands of high-performance and modified engines. Ideal for engine rebuilds, performance upgrades, or routine maintenance where reliable sealing is critical.
