You will most likely lose some strength if you cut, I agree with Colin above I would just go in at 180 (get a little fat and do 185 :). If you focus on increasing your 1RM with an occasional high rep set, even once a month or so at a minimum, your 225xreps will go up. In other words bench 325 compared to 305 and I promise the 225 for reps set goes up. You only need to specialize on that when you can get 225 for 20 or more reps. Remember though speed is key when repping out. It will be after you do the max on the bench (not right after, you will have some rest). Good luck, make sure you practice the pause and a press command if they give it to you and know any other rules going in.
