Product Details
If you're rebuilding the top end of your 1985-1991 Toyota Corolla with the 4A-GE engine, a quality head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring reliable performance and preventing leaks between your cylinder head and engine block.
Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block setups. This gasket has a compressed thickness of 0.098 inches and an 83mm bore, specifically designed for the 16-valve 4A-GE engine. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.
