Does anybody know if this is the correct oil pump replacement for an n/a 3V?

I have to swap the heads so I picked up the new style '08 heads and while I'm there I have a few questions. Since it's going to be a basic bolt on 320rwhp n/a engine, is it absolutely necessary to use ARP head studs and Cometic head gaskets or will I be just fine using regular head bolts and head gaskets? I know it's better to be safe then sorry but were talking about an extra $600 that can possibly be used elsewhere.
