yes these are the american made headers, i bought them brand new but not in a package from a customer at my dealer who decided not to use them, i wasnt 100% what exact part number they were but he did say 409SS american kit. i installed them on my camaro for about 5000miles, i decided to get a full kooks system to use on my new 427 setup. the headers bolt right up using stock ypipe band clamps. i reused my stock gaskets and bolts because the car was brand new. when you take off your manifold/cat assembly and install the headers and connect them to the stock catback
Using stock band clamps.
