Re: '71 air cleaner & manifold help
Not to be rude, but why headers? That looks like a stock engine, so you're not likely to see any performance gain. But what you'll get in return is more noise inside the cab, periodic leaks, and more heat in the engine compartment.
I would go with the dual exhaust without the headers if it were my truck.
Oh, and welcome to the board.
