Product Details

The Mr. Gasket 5780G Ultra-Seal Head Gasket is engineered for high-performance street, drag race, and oval track applications where reliability is critical. This premium head gasket features advanced multi-layer steel (MLS) construction designed to withstand extreme cylinder pressures and temperatures.

Key Features:

  • Five-layer composite construction with graphite core and perforated steel outer layers for superior sealing
  • High-temperature silicone coating ensures complete sealing of engine fluids under demanding conditions
  • Will not brinell (indent) aluminum cylinder heads, protecting your engine investment
  • Provides excellent stability, compressibility, and high-temperature endurance
  • Ideal for naturally aspirated and forced induction applications

The Ultra-Seal design combines the flexibility needed to conform to minor surface imperfections with the strength to maintain a reliable seal under high combustion pressures. The perforated steel layers provide exceptional combustion sealing while the graphite core offers optimal heat resistance and compressibility.

Good price

The listed matching vehicles were a little vague, still a little uncertain if the part will fit, will have to find out for sure once it arrives

All pieces ordered were shipped promptly and arrived in very great shape. I will be ordering from this site again.

Good prices. Good communication.
