1983 Pontiac Firebird Performance Engines

Mr. Gasket High Performance Thermostats are designed to resist large variations of coolant pressure at high RPM (revolutions per minute). This allows them to fully open at correct temperature consistently regardless of engine RPM. The design also provides the high flow that engines operated a higher RPM need. This thermostat also features a copper/brass construction to further resist corrosion. Mr. Gasket High Performance / High Flow Thermostats are suitable for street, drag race, or oval track applications.

Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids.brbrA typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.

Product Features:

• Gasket bore – 4.060″ Thickness – .040″
• Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
• Optimized sealing embossments seals extreme cylinder pressure
• Provides excellent stability and reduces cylinder bore distortion.
• Proprietary polymer coating ensures the micro seal of engine coolant and oil fluids.
• Ideal for supercharged, turbocharged, nitrous oxide and extreme compression ratio engines
• For high-performance street, drag race and oval track use

Mr. Gasket Ultra-Seal Head Gaskets are a five layer (graphite core/perforated steel outer layers) composite construction.
