Cometic Toyota 4A-GE 81.5mm Bore .056in MLS Head Gasket 20 Valve

If you're rebuilding the top end of your Toyota 4A-GE engine, a quality head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of the 20-valve 4A-GE, ensuring a solid seal between your cylinder head and engine block.

This gasket features an 81.5mm bore, matching the standard bore size for many 4A-GE engines, and a thickness of .056 inches. The MLS construction uses multiple layers of stainless steel with a specialized coating to provide excellent sealing under high pressure and temperature conditions. This design offers improved durability and resistance to gasket failure compared to traditional composite gaskets, especially in performance applications.

When installing this gasket, ensure both the cylinder head and block surfaces are clean and flat. Refer to the manufacturer's installation instructions for proper torque sequences and specifications to achieve the best seal.
