Cometic C8328 MLS Head Gasket Compressed Thickness - 030

The Cometic C8328 is a Multi-Layer Steel (MLS) head gasket constructed from multiple layers of stainless steel for additional strength over traditional gaskets. With a .030" compressed thickness, this is a high-compression option designed for performance applications where reducing combustion chamber volume is desired.

Advanced MLS Construction:

• Features a stainless steel center sandwiched by two Viton-coated spring steel embossed outer layers for a seal that can withstand the shearing forces created in the head gasket environment
• Each MLS head gasket is coated with a .001" thick Viton rubber that is bonded to the outer stainless steel layers
• Contains load-controlled embossments that help conform load distribution across the sealing area
• Creates an exceptional seal by requiring less clamp load and resulting in less bore distortion

Installation Requirements:

• MLS head gaskets require smooth, flat and true head and deck surfaces to seal
• A surface finish of 50 RA (roughness average) or finer, is recommended for a proper gasket seal
• Cometic Multi-Layer Steel (MLS) head gaskets go on dry because they are coated with a sealant
• No sealants or re-torque is required when properly installed on prepared surfaces
• Piston-to-head clearance should be verified (.030"-.032" optimum) before using .030" gaskets

MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. The .030" thickness provides increased compression ratio compared to thicker gaskets, making this an excellent choice for naturally aspirated performance builds and racing applications. Verify bore size and piston-to-valve clearance before installation to ensure proper fitment for your specific engine application.
