I set 2-200 amp panels inside a house and a 320 amp meter base outside am I going to need a meter panel combo for the main panel and use both of the inside panels as sub panels. Right now I have just the meter outside both panels has main breakers

Well, aside from the fact that I can hardly understand your post, I think I get the drift.

Typically I would just use a 320A meter base with double lugs on the load side. Then run two runs of 4/0AL or 2/0CU to the panels.
BOTH inside panels are MAIN panels in this case.

I set 2- 2oo amp main breaker panels in a house and ran 4/0 4 wire to the meter base which is 320 amp meter base the panel upstairs is about 30 ft away from the meter will i need another disconnect at the meter for that panel

This would have been good to know from the start. Yes you will. It will need to be inside where the other main panel is.
