I don't know why the felpro gasket so expensive, and I don't want to go with the cheaper ones because the job might not be hard, but it takes quite a bit of time.. the gasket itself (Fel-Pro) is not that old.. I installed it in 2022, then I reused it in 2023.. should have known reusing it was a bad idea.. but it's too damn expensive for what it is 😂..
