340 HP's vs headers

I like the stock look, trying to keep it "looking" stock. I wanted a 408 that looks like a stock 273 4 barrel. I always had problems w headers in the past, thats prob what soured me on em now. I am starting to wrap my mind around the hedman tight tube block huggers, and maybe keeping those stock 340s for my sons mild 318 future project. I can prob sand blast em and use the high heat cast iron paint to camouflage em a little bit.
