Here’s what I used, I didn’t replace with GM parts that would only rust again. Note that the ARP #400-8014 studs are M8-1.25mm.
For the studs: ARP #400-8014 (8 studs in kit, only use 7)
For the manifold bolt: ARP #771-1002 (use the beveled washer from the stud not used in the prior kit)
For the heat shield bolts: ARP #771-1017 (16mm long)
For the extra nuts for the heat shield: ARP #400-8311 (This is a bubble pack of two nuts. I couldn't find this part so I bought the individual nuts which is ARP #400-8310)
I also used Permatex 2600 degree anti-seize on the threads.
