    Modern Cylinder Heads Require a New Type of Gasket

    Why use a Fel-Pro Multi-Layer Steel Cylinder Head Gasket? Because more power per cylinder, higher operating temperatures, and thinner head and block castings demand a modified gasket. MLS Gaskets are stronger, more forgiving, and capable of sealing despite movement between the head and block. Such motion results from: lighter, thinner aluminum head castings that are more susceptible to thermal expansion; computer controls that can dramatically increase engine output; reduced clamping force that prevents stress points and cylinder bore distortion.

    MLS Technology was developed to overcome sealing challenges. The number of layers in an MLS Gasket ranges from two to five, depending on the engine's sealing characteristics. Generally, the more layers, the more motion the gasket endures. There are multiple solid layers of heat-treated stainless steel separated by a very thin rubber coating, and the layers are either active (absorbing motion between the head and block) or shim (giving the gasket its correct compressed thickness). Gaskets are sold each.

    Features
  • Stainless steel maintains shape
  • Survives higher combustion pressure
  • Withstands "scrubbing" between head and block
  • Functions at a wider range of operating temperatures
  • Strategically-placed sealing beads eliminate leak paths
  • "Stopper" layer provides superior primary combustion seal

    Rated 5 out of 5 by from Great sealing gasket for 400 block! I bought this gasket to ensure that the cracks between the steam holes and head bolt holes on my 70's 400 block would be sealed by the rubber-like material of this head gasket - so far no leaks. However, imagine my surprise when I opened the almost $70 package and only found 1 head gasket! Other brands are even more expensive!

    Rated 5 out of 5 by from perfect for a high-performance race motor Mls is the only way to go. So far i have use cometic, felpro and speedmaster and have had no troubles with any of them on a 750 hp small block chevy race motor. Also all have held up to a 250 hit of nitrous
