Speedmaster PCE348.1035 MLS Head Gasket Chrysler Dodge Big Block 4.500" Bore 0.040" Thick

The Speedmaster PCE348.1035 is a multi-layer steel (MLS) head gasket engineered for high-performance Chrysler and Dodge big block engines with a 4.500" bore diameter and 0.040" compressed thickness. Built to withstand extreme cylinder pressures and temperatures, this gasket is the proven choice for serious power applications including heavy nitrous, forced induction, and naturally aspirated builds.

Key Features:

• Multi-layer steel construction with high-pressure laminate design for superior strength
• Internal embossments that expand under heat to create an enhanced seal during high combustion pressures
• Engineered to handle extreme shearing forces between aluminum heads and iron blocks
• Compatible with both aluminum-to-iron and aluminum-to-aluminum block configurations
• Superior torque retention and minimal distortion compared to conventional composite gaskets
• Maintains consistent contact pressure between cylinder head and block throughout engine operation
• 4.500" bore diameter with 0.040" compressed gasket thickness

MLS gaskets are the preferred solution for high-horsepower applications where conventional gaskets fail. The steel laminate construction resists blow-out and maintains seal integrity even under the demanding conditions of turbocharged and supercharged engines. Ideal for engine builders and performance enthusiasts who demand reliability at extreme power levels.
