440 power gains/ aluminum head advantages?

Marathon cam degreeing session?
lol basically. been pretty hot out and i've been trying to figure out how i'll degree it with my setup. i finally understood and got a consistent reading while degreeing. my intake lobe centerline is 110 degrees. recommend intake centerline for my cam is 105. is there a huge loss of power here being 5 degrees off? i'm not sure how much is too much but from what i've read .5 degrees tolerance is ideal.
