okay, i'm doing a set of 5.3 heads, going to raise the compression up to 11:1, the car puts down 433 hp now with stock 241's and a cam. I'm probably going to do a 150 shot on it in the next month or so as well. so my question is: ARP bolts be good enough, or should i go with the studs for this kind of power?

 

Studs are extra safety but ARP bolts will do the job fine.
