820's or 550's in the primaries?

For a track car, idle and passing emissions isn't a concern. Is there any other reason to use smaller primaries besides those reasons? If not, I'll toss my 820's in the primaries. If so, give me reasons why I should use the 550's.

Car is a 13bt block (mostly) with FD upper/lower intake and throttle body, T04B, Wolf 3D, trailered to and from the track.

Oh yea, I'm gonna have some of those 1680's in the secondaries, and I'm shooting for 425 rwhp ... but I'd like to be able to support around 500 rwhp.
