Just got my engine back

though I'm broke I'm happy, but i have a few last things to get to put it together, have the gasket kit and all the bearings and timing belt, still need the water pump and oil pump, and all my main and head bolts.. Theres a few factors here, if I can buy all these parts from one place that'd be great, especially with fast shipping, so amazon has me there cuz i have prime with 1 day shipping.. The engine is only going to be around 400hp at the crank this time around, once I pay it off I'll go bigger turbos, but the engine is built to handle good power(wiseco/eagle stuff) my goal is around 700 at the crank, 600 wheels, what I wanna know is with that goal in mind will I be ok with stock mains and heads, or do I need to go with arp or some other brand of bolts? Cuz I'd rather not if I don't have to
