Product Details

The Speedmaster PCE348.1040 is a high-performance Multi Layer Steel (MLS) head gasket engineered specifically for Ford Modular 5.0L engines. This left-side gasket features a 3.701-inch bore diameter and is designed to withstand extreme cylinder pressures and temperatures in high-horsepower applications.

Key Features:

  • Multi Layer Steel (MLS) construction with high-pressure steel laminate design
  • 3.701-inch bore diameter for precise fitment on Ford Modular 5.0L engines
  • Internal embossments that expand under heat for superior sealing
  • Engineered to handle high shearing forces between aluminum heads and iron blocks
  • Superior torque retention and minimal distortion compared to composite gaskets
  • Maintains constant contact pressure during extreme engine operation
  • Ideal for heavy nitrous, turbocharged, and supercharged applications

This MLS head gasket is proven to perform in demanding conditions where conventional gaskets fail. The multi-layer steel design excels at maintaining seal integrity under the extreme combustion pressures generated by forced induction and nitrous oxide systems. Compatible with both aluminum-to-iron and aluminum-to-aluminum block configurations, this gasket delivers professional-grade sealing for serious performance builds.

Application: Ford Modular 5.0L engines (left side)
