Solid set up it seems, compression looks like a touch over 9:1 and that cam is going to have great low-end torque, those heads look to flow better than I'd expect. I think you will out do your goal of 375 hp, my guess is 386, but the real story is in the torque I think you will put down something like.... 447. So thats my guess 386HP/447TQ. Good Luck!
