Product Details
If you're rebuilding the top end of your 1987-1992 Toyota Supra with the 7M-GE or 7M-GTE engine, a reliable head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these engines, ensuring a strong seal between your cylinder head and engine block.
Cometic constructs this gasket using multiple layers of stainless steel for increased strength and resistance to shearing forces, especially when mating aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and provides excellent sealing even on varied surface finishes. The compressed operating thickness is .066 inches with an 84mm bore, designed to fit your specific 7M engine application without needing additional sealants.
This gasket is a solid option for both stock and modified 7M engines. Its robust construction helps maintain consistent sealing under higher cylinder pressures, making it a dependable choice for your engine rebuild.
