Cometic C9914 EST Top End Gasket Kit for Edelbrock 1200 Sportster

The Cometic C9914 is a complete EST (Extreme Sealing Technology) top end rebuild kit specifically engineered for Edelbrock 1200cc Evolution Sportster engines from 1991-2000 with 5-speed transmissions. EST stands for 'Extreme Sealing Technology', representing Cometic's advanced approach to high-performance gasket design for modified engines.

Advanced Gasket Technology:

• Head gaskets included with these kits are Cometic's 'MLS' (Multi-Layer Steel) gaskets, providing superior sealing under high compression and extreme temperatures
• SPS (Spring Steel) Gaskets are made from embossed stainless steel, coated with a high temperature viton material that virtually eliminates leakage
• EST gaskets are used in critical sealing surfaces such as rocker box and cylinder base gaskets
• The SLS (Single-Layer-Steel) cylinder base gaskets and SLS rocker cover gaskets used in these sets are .020" thick and have .001" of high temperature viton rubber coating on both sides

Complete Rebuild Kit:

• Kit comes with all gaskets, seals and o-ring for a complete top end rebuild
• Multi-Layer Steel (MLS) head gaskets for maximum compression sealing
• Viton-coated base and rocker box gaskets for critical sealing surfaces
• High-temperature exhaust gaskets
• All necessary O-rings and seals

Today's lightweight engines are producing more horsepower, higher cylinder pressures, clamp loads and extreme temperatures, making professional-grade gasket materials essential for reliability. This kit is specifically designed for Edelbrock aftermarket cylinder applications on Sportster Evolution engines, ensuring proper fitment and sealing for performance builds.
