I think any decent set of long tube headers will flow enough for you. What mods are you planning that you would need an unusually large diameter header? 1 3/4" primaries are about the biggest standard size you will find I think. American Racing headers are usually regarded as some of the best, but they are expensive.

1 5/8'' (normal size is fine for boosted), only gonna see an improvement with a larger diameter primary like the 1 3/4'' is high boost high hp applications(600+hp 15+ psi)
