About this part

Product Details

If you're rebuilding the top end of your 1987-1992 Toyota Supra with the 7M-GE or 7M-GTE engine, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines.

Cometic 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 temperatures up to 482°F (250°C). This combination ensures a reliable seal between the cylinder head and the engine block, whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block. The gasket has a compressed thickness of 0.051 inches and is designed for an 84mm bore, fitting your Supra's specific needs without requiring additional sealants.
