How to: Install headers on a 5.0

At first no. They actually seemed to have lost power, especially when I first drove it straight piped up the hill to the exhaust shop. On my way back, I had dual 3" pipes going into a single muffler with a single 3.5" exit, it felt better but like I had lost noticeable power below 3500rpm.
Yesterday I loaded my 5 star 91 performance tune. It seemed better but still not better than before. It was hesitant, and I thought I felt a few misses while cruising. I drive it a few times today and it seems to get better every time I drive it. On my way home early today I passed my neighbor who has a 454 in his old truck that's bored .060 over and has a cam. I about got sideways in first gear and hit second with some serious power(not shift shock though). On my way home just a few minutes ago I decided to see how it felt with a little power breaking. Let's just say that smoke shows are a cake walk.
Part throttle was starting to see some serious improvement. At first it felt like I had lost power, like I said earlier, but I seam to have gained that back and then some. I am running too big of an exhaust for N/A but I feel if I gave it more time, especially if I ran a smaller exhaust more suitable for N/A I'd really love the headers, but I'll never know because tomorrow I should be able to install my supercharger.
Oh, the best part! The SOUND! Everyone agrees, it sounds like a classic cammed bigblock. It most reminds me a 440 Chrysler industrial engine that my dad has in a bankout wagon. The difference is mine revs like hell so it has that high power rasp that older engines like the 427 make with minimal muffling. I can't get my phone to get even close to capturing the sound, it's kind of intoxicating.
Black Ceramic. They said it was 1800 degree rated which was the highest they offered so I went with that.
