ARP with Chevy iron heads
which studs are you guys using on your blown engines...does the head type matter?

ARP , for everything
the nut type.
I have bowtie aluminum heads decked .125.
Keith, ARP for all motors. When you ask about 'head type', do you mean the nut 'type' ( 6 or 12 pt), or the engine head type?
I always use 12 pt nuts for clearance issues, and with aftermarket heads, either steel or aluminum WITH RAISED PORTS, you need longer studs for the center 8 (4 each side).

any idea which ones I will need to for these heads?

do you think the .125 milling will have any effect?
