Cometic C10016SM-027 MLS Cylinder Head Gasket .027" Compressed Thickness

The Cometic C10016SM-027 is a Multi-Layer Steel (MLS) cylinder head gasket with a .027" compressed thickness, engineered for high-performance street and racing applications. Cometic's MLS construction delivers a race-proven seal trusted by championship-winning engine builders across NHRA, IHRA, NASCAR, and beyond.

MLS Construction Technology:

• Three layers of stainless steel — selected for superior strength, rebound capability, and corrosion resistance
• Embossed outer layers coated with a .001" thick Viton (fluoroelastomer) rubber bonded to the stainless steel for chemical and high-temperature resistance
• Load-controlled embossments conform load distribution evenly across the sealing area, reducing bore distortion
• Active combustion seal on multiple layers for maximum blowout resistance under extreme cylinder pressures
• Withstands shearing forces created between aluminum heads and cast iron blocks

Key Specifications:

• Material: Multi-Layer Steel (MLS)
• Compressed Thickness: .027" (0.686 mm)
• Layers: 3
• Part Number: C10016SM-027

Installation Notes:

• Installs dry — no additional sealant required; adding sealant can hinder gasket performance
• No re-torque necessary when properly installed
• Requires smooth, flat, and true head and deck surfaces; a surface finish of 50 RA (roughness average) or finer is recommended
• Always follow fastener manufacturer torque specifications for proper clamping load

The Cometic C10016SM-027 MLS head gasket is an ideal choice for naturally-aspirated, forced-induction, and nitrous-fed builds where reliable, long-lasting combustion sealing is critical.
