I am getting ready to install my FFR stainless headers on my Dart 427 w/AFR heads, I have read multiple ways of doing this so I am little confused on what the best method is. FFR sent me Mr Gasket aluminum gaskets with the supplied FFR bolts. I would like to hear how you guys are doing this and have had success with them not backing out or leaking. If posible I would prefer to just use the header bolts FFR gave me seeing as I already have them.
