Performance Benefits:

• Ideal for both aluminum-to-cast iron and aluminum-to-aluminum block/head combinations
• Withstands shearing forces created by dissimilar metal expansion rates
• No re-torque required after installation
• Promotes even torque distribution across the sealing surface
• Reduces bore distortion for improved ring seal and engine longevity
• Excellent resistance to coolants, oils, and combustion gases

This MLS head gasket delivers the reliability and performance needed for high-output engines, from street performance builds to competition applications.
