Review on Remflex 3022 Exhaust Gasket Engine by Ethan Delaney

These gaskets seal a lot better than any other! I've used them on two of my 7.3L Powerstroke engines and a 5.4L Ford Modular when installing headers. They don't need to be tightened and they don't leak at all. Just follow the factory tightening and torque sequence and you'll be fine.
