Fel-Pro Performance Head Gaskets

Forged in the fires of high performance engines, Fel-Pro Performance head gaskets are quite literally created to tame the fiery combustion chambers of up to 1,000 hp engines. Reinforced with KEVLAR® fiber and engineered to give you a perfect seal that can withstand combustion pressures of 1,500 to 3,000 psi, these gaskets are bred for high performance. They have a conformable anti-stick coating—and are constructed with pre-flattened copper or steel rings for easy installation, while also giving them the strength to tame your beastly powerplant. The anti-stick coating ensures easy removal and cleanup on frequent rebuilds, but also aids in micro-sealing minor surface irregularities. When rebuilding your engine, use the parts you wish were in it to begin with. Put a set of Fel-Pro Performance head gaskets in that engine—not only to help it perform better today, but to make your next engine project that much easier.

Cometic MLS Head Gaskets

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Mr. Gasket Ultra-Seal Exhaust Gaskets
