Made from a flexible graphite compound used in demanding industrial environments for decades, the gaskets compress to fill flange irregularities and resist the high temperatures found in exhaust systems far better than traditional composite or rubber-bound parts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat engines and years will these gaskets fit?\u003c\/h3\u003e\n\u003cp\u003eThese gaskets fit square-port Mopar V8 applications where the flange opening measures 1-7\/8\" by 1-3\/8\".

The material is proven in industrial service at very high temperatures, and in automotive use it compresses to compensate for flange imperfections, reducing the need for repeated retorquing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard thickness: 1\/8\"; designed to crush about 50%\u003c\/li\u003e\n  \u003cli\u003eFills surface pits up to 1\/16\" for a consistent seal\u003c\/li\u003e\n  \u003cli\u003eNo rubber binders means less long-term deformation or shrinkage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I reuse these gaskets or apply sealant with them?\u003c\/h3\u003e\n\u003cp\u003eRemflex recommends treating these gaskets as single-use components to ensure an uncompromised seal; while some users have reported reuse, reliable sealing is achieved with new gaskets. Do not apply any sealant: most sealants burn away and can create gaps that lead to leaks, while Remflex gaskets are rated to withstand temperatures that exceed typical sealant performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSold as a set of two gaskets for manifold\/header flanges\u003c\/li\u003e\n  \u003cli\u003eDo not use adhesives, RTV, or other sealants\u003c\/li\u003e\n  \u003cli\u003eReplace gaskets whenever flange surfaces are disturbed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation tips and torque guidance should I follow?\u003c\/h3\u003e\n\u003cp\u003eBecause Remflex gaskets are designed to crush and conform, the recommended bolt torque is lower than many factory specifications; specific torque guidance is printed on each package. Proper installation includes clean, flat flange faces and progressive, even bolt tightening to the suggested torque to achieve a uniform crush and avoid distortion.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClean mating surfaces thoroughly before installation\u003c\/li\u003e\n  \u003cli\u003eTighten bolts evenly in a crisscross pattern to the package torque value\u003c\/li\u003e\n  \u003cli\u003eInspect flanges for warpage or deep damage and address as needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The Remflex 6002 gaskets suit classic Mopar owners, restorers, and performance tuners who need a high-temperature, stable exhaust seal for square-port V8 manifolds or headers. If you value durable materials that resist heat-related shrinkage and want a gasket that conforms to imperfect flanges for dependable sealing without aftermarket sealants, this set is designed for your project.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this gasket fit a 440 Mopar engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
