About this part

Product Details

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

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different block and head materials, including aluminum and cast iron. The center layer is stainless steel and can be varied in thickness to meet specific build requirements; this particular gasket has a compressed thickness of 0.036 inches and an 84mm bore, with an overall thickness of 0.098 inches.

Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward. This gasket is a solid option for both stock and modified engines where a strong seal is needed.
