I'm 6'4 and 205 lbs. The key is the anthropometric chair and the fit-check. They will sit you in a weird chair at NAMI and measure all of your various parts (keep your mind out of the gutter). Height, reach, legs, etc. My "problem" was the femur (butt-to-knee) length. Squeeze yourself as small as possible, until it hurts. Don't let it show, though.
You'll be classified as "in norms" or "out of norms". I may have the terminology wrong, but that's basically it. If you're out of norms, they'll "fit-check" you. Simply put, they take you to a plane and see if you fit in it and can move all of the controls and flip all of the switches. If you fit, you pass. They'll start with training aircraft. It doesn't matter if you fit in a Hornet if you don't fit in a T-34/T-45 since you have to fly those first anyway.
The key to the fit-check is selling the aviation physiologist. Act comfortable and tell him how much it feels comfortable. Obviously, if you CAN'T fit and work the controls, don't lie (or lie in general for that matter). I'm just saying that how you act in the check has a great influence on it.
I was NPQ in the TA-4J, which made me ineligible for jets. The paperwork got "lost" (don't ask how, it's a very long story) and I had to recheck. I crammed myself in the chair to the point that I didn't even pop for "out of norms" the second time, so fit-checks were not required. I wound up getting jets (got winged flying the TA-4J) and now fly Harriers. I can fit and fly in any jet/helo in the inventory. I've sat in nearly all of them and flown some, too.
A word of caution: don't overly game it. Sell the fact that you fit, but if you really don't think that you can move all of the controls (this won't happen at your size) then don't fly it. Also, if you think that you can get yourself NPQd from helos/props etc to ensure jets (or whatever) it will likely backfire and get you NPQd altogether. I do know 1 guy who had to go C-130s because of his height, but honestly, I think he BS'd them. He's not much bigger than I am.
At your size, I think you'll be fine for whatever you want. All of the cockpits are fairly large and the pedals/seat moves to accomodate you. Hope this helps.
