The stock headbolts should be replaced, either with another set of stockers or with some ARP studs (use the SR main stud kit, you'll need to reuse an old washer on one of them as the one above the water inlet/outlet will be a tad higher up). You'll need a 1/2" IIRC socket that is either very thinwall 12pt or get one and grind down the outside to fit in the head, if you go w/ ARP. the ARP bits are reusable but not cheap, but getting new OEM bolts is going to be a PITA to wait on..
