Headers will be interesting to say the least, someone just posted on this recently so do a search.

I have found out the GTO headers for 68-72 3 tube models will fit the 455. Anyone else use these? I hear its just a bolt in. Except the oil filter has to have a remote unit installed which I had already planned on. thanks

They may fit the motor, but will they fit the Firebird chassis?
