80mm or 85mm means you're looking at aftermarket, which you should not do.
For either an LS1 or LS6 intake, go with a ported stock throttle body. They're cheaper and don't cause drivability issues like most aftermarket. Also, a ported stocker will make the same if not better power. The stock LS1/LS6 intake doesn't have a large enough opening to properly accomodate anything larger than 78mm.

Just port your stocker until you have an intake that can utilize the larger TB. You could send your LS6 intake to TPIS and have them make it a 90mm intake. It's a decent upgrade.
