With the stock motor, the 1 1/2 primaries will bump up the off idle and midrange torque better than a bigger header will. Youre trying to improve the flow with-in the engines operating range. This is one of those areas where bigger is not better.
If your engine had a compression bump, better flowing heads, a larger cam, matched intake, then you would want the larger headers.

Hooker makes a great fitting header, they offer different colors of ceramic coating, and they last. I got 25 years out of my last set of Hookers.

Make sure you read the warrenty of any header that you decide to buy, not all ceramic coatings are the same, and some are not guarenteed.
