Are you shooting for 560 to 580 HP at your altitude? That would figure out to be an equivalent of around 640 to 660 HP for me a state east of you. I think that is going to need the big .4ish lobe and the big ratio rockers for that, and more than .6 lift.
If that 560HP to 580HP is a sea level equivalent and you want to be about .6 lift it makes sense to stick with 1.5s HS rockers and a .38 to .40 lift lobe.
