Speedmaster PCE348.1039 Ford Modular 5.0L MLS Head Gasket Right Side 3.701" Bore

The Speedmaster PCE348.1039 is a high-performance multi-layer steel (MLS) head gasket engineered specifically for Ford Modular 5.0L engines. This right-side gasket features a 3.701" bore diameter and is designed to withstand extreme cylinder pressures in high-horsepower applications.

Key Features:

• Multi-layer steel construction with high-pressure laminate design for superior sealing
• 3.701" bore diameter optimized for Ford Modular 5.0L right side
• Internal embossments that expand under heat to enhance sealing at high combustion pressures
• Engineered to resist extreme shearing forces between aluminum heads and iron blocks
• Maintains consistent contact pressure during dynamic engine operation
• Ideal for turbocharged, supercharged, and heavy nitrous applications

Performance Benefits:

• Better torque retention compared to conventional composite gaskets
• Reduced distortion under high cylinder pressure and temperature cycling
• Superior sealing in both aluminum-to-iron and aluminum-to-aluminum block configurations
• Proven durability in extreme power applications

MLS gaskets are the preferred choice for serious performance builds where reliability under extreme conditions is critical. The multi-layer construction allows for thermal expansion while maintaining an effective seal, making this gasket ideal for engines producing significantly higher than stock power levels.
