I want headers for my 350TBI. Other than the O2 sensor, is there any thing else that I need to worry about? I know there are metal lines going into the top portion of the manifolds, is that going to pose a problem if it's not hooked back up? Heck, I don't even know what that stuff is. I have true dual with 40 series Flowmasters and I just want to add headers. I don't need a set of $300 jet coated heat resistant blah blah blah..........get my drift? Headers, that's it, and whatever I need to make the TBI still work properly. Thanks guys.
