Exhaust for stock 272 Y-Block....what to get?

[Metal Ghost]

Hey there everyone. I posted this in the Ford community, but I wanted to get the question out to the big board as well.

Wanted to get some input on what maybe I should get in the way of new exhaust parts. Maybe even some of you are running some of the parts I plan on choosing between. I'm looking at buying new headers and mufflers from Red's. I'm running a pretty stock 272. I'm looking at moving from my current crossover set-up to a dual exhaust.

For headers, I have the choice between these or these. First, is the dual tube overkill given a stock engine? If so, do I go for the 1 3/4 or 2" monotube (why not 2'', right? I know bigger isn't always better, but 2'' seems fairly modest) Finally, again given the fact that it's a stock enging, is the metallic-ceramic coating really overkill? I mean we're basically talking the same price for the coating as the headers themselves, but truth be told I am keen to lower the temp a bit under the hood (not overheating now, but at stops I see the gauge rise a bit).

As for the mufflers, I'm trying to decide between the Porters and Smitty's. I've been told that the Porters have a bit of a deeper sound and are constructed with thicker steel, but they're also twice (almost 3 times) the price. Anyone running these....are they worth it?

Thanks for the insight guys! I want to do this right, but I'm looking at about a $400 differential between the lowest priced options and the highest, and I'm not keen to throw money away that I kind of don't have!
