Can somebody please tell me the correct ARP header studs order code?

I need studs for my 1983 engine. There are more than one kit at ARP that are meant for the V6 Turbo. Can somebody please give me the correct code for the ones I need? I have found 123-5401, 120-1412 and 120-1402. So I have no idea what kit I need.
