First have to state the obvious but headers are a b to install in these cars......now that thats out of the way. I am installing some ARH in my car and want to know if you guys are using copper silicon gasket sealant when you install them or are you jjust installing them straight on. Just asking because there is a CJ PP you tube video where they install them with the copper gasket stuff. just thought Id ask before I get goo on there I dont necessarily need. Thanks!
