No idea about the headers, but your truck is going to be an ANIMAL.
Actually I think Quik had some Kooks headers that were 1 7/8 stepped to 2. Pretty sure on a 2wd the Kooks f body headers will fit.

Saw a header test a couple of years or so back, maybe Car Craft or Hot Rod. I would definitely do 1 7/8 with your setup.

i would go 1 7/8 kooks or 1 7/8 stepped 2 inch if you can afford them Flaco is running them in his. you need the big diameter on larger motors. TSP just did a test. 1 3/4 vs 1 7/8 and up till 4800 rpms they were the same. from 4800+ the 1 7/8 gained nicely on a stock motor. you can find this test in the dyno section on tech
