I'd do flat bench d-bells as heavy as you can first, that will blast your entire chest top to bottom, and the range of motion with d-bells is far better than that of barbells. You also have to use all of the stabilizer muscles! (use a 6-8 rep range here)
Next, I'd do 4 sets or so of pre-exhaust incline presses. Pre-exhaust your pecs w/flies or cable crossovers, then IMMEDIATELY run over to the incline bench using d-bells again, or incline hammer strength works good for this, and complete one set there (8-10 reps is good) Do these super-sets 4 times for that upper chest, after you do 4 sets of heavy flat presses first.
Don't neglect the pwo meals either or your diet at all for that matter, or it won't matter what you do in the gym.
