Exhaust Gasket Set BBF FE 390GT/GTA

The Remflex Exhaust Gasket Set BBF FE 390GT/GTA (Part #3051) is a purpose-engineered exhaust header gasket pair designed specifically for Ford FE-Series big-block engines, including the legendary 390GT and 390GTA variants. These graphite gaskets feature 1.188 x 1.813-inch square port geometry and are engineered to seal header-to-cylinder-head interfaces on universal-fit Ford headers without requiring modifications to factory or performance manifolds.

Graphite construction in exhaust gaskets offers superior heat resistance and conformability compared to traditional steel or composite materials, critical for the high-temperature, pressure-cycling environment of header applications. The square port configuration matches the port shape of FE-Series cylinder heads precisely, minimizing turbulence at the header inlet and preventing exhaust leakage that would compromise engine efficiency and increase underhood noise. The pair configuration ensures you have matched gaskets for both cylinder banks. Remflex gaskets are engineered to survive extended thermal cycling without delamination or permanent compression set, a common failure mode in budget alternatives.

This gasket set is essential for resto-mod builders, vintage muscle car enthusiasts, and engine rebuilders working with 390GT, 390GTA, or other FE-Series applications requiring OEM-correct or performance header fitment. Whether you're installing reproduction headers on a restoration or upgrading to modern tubular headers on a street or competition build, proper gasket selection prevents exhaust leaks that cause performance loss, excessive heat, and diagnostic challenges. Installation requires only standard hand tools and takes less than an hour per side.
