Are ARP head bolts really needed for a mild build?

I'm building a pretty mild .060 over 340, kb243's, h beams, ported j's w/ stainless valves, chambers at 66cc, .550 lift solid roller, around 10.5:1 comp 4 speed, 3.9 gears. Planning to spin it to about 7k at the most. I'm not one to cheap out on things like fasteners, but after looking at the stock bolts and realizing they are pretty beefy, im not too sure if they really need to be replaced. They are not stretch bolts, and im thinking some arp moly lube on the threads and let it rip. Anyone have any problems with stockers?
