Mr. Gasket – Mls Head Gasket (Part No.3132G)

Mls Head Gasket

from

$102.99
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 – 4.165 inch: Compressed thickness – .040 inch
  • 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

VALVE SEALS, TEFLON 3/8" 1 ST

from

$31.99
COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:
  • Work with .530″ guides and 3/8″ valve stem diameter
