    I'm taking off my 2-1/8 headers, down sized the motor a little. Right now making around 560hp. Looking at either 1-7/8 or 2inch tubes. Just asking you big block guys what you think. My choice of headers going back as always been Hooker. Appreciate your advice.

    1.75 should be all you need.

    Big enough to cover the port and hold a gasket.

    I'm using the Hooker Super Comps in my truck (same crazy-big primaries as you are taking off). Only reason I went that big was to cover the HUGE exhaust port on my AFR heads, not because I needed anything that big for the HP level I'm making, which is probably not even as much as you are with your "downgraded" combination.
