You don't loose mileage from leveling or lifting... you loose mileage with the larger tires. With that said, when geared properly, you can get near stock mileage. My 03 5.3L 4-speed with 4.10 gears ran 35" tires with a 6" lift and I achieved all day long 14-15mpg intown and 18-19mpg highway as long as I kept the speed below 70mph.
So... I assure you with 100% you can crank your current torsion bars to get a full 2" of lift out of the front without issue. You can run 285's after but you will need some kind of tune to adjust for the larger tires. If you don't, it will throw off your speedo, your shift points, and your mileage. I don't recommend running larger keys to achieve more lift than that. You WILL start having issues with ball joints, CV joints and tie-rod ends if you over extend your front suspension. And anytime you crank the torsion bars, you'll need an alignment.
You can Take it or leave it. Good luck.
