About this part

Product Details

If you're rebuilding the top end of your 1985-1991 Toyota Corolla, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built for the 4A-GE engine, featuring an 83mm bore and a compressed thickness of .051 inches. It's designed to handle the demands of high-output engines, ensuring a reliable seal between your aluminum or cast iron block and aluminum head.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes without needing additional sealants. The center layer is uncoated stainless steel, allowing for precise thickness control.
