Head bolts for a 6 bolt bottom w/ a 2G head?

[Game Over]

I am doing a 6 bolt swap, but using my 2G head. I need to order up some head bolts. I tried searching but I came up empty handed. I have a good idea, but want to see what you guys tell me first.

Thanks

some people use ARP head bolts but you need to machine the 2G head to fit

I used a set of ARP studs but you can use the 1g head bolts if you wanted! Just drill out the holes on the head (CAREFULLY) so the bolts or studs will fit! I used a 12.5 mm bit and worked great!

So the head bolts need to be 12.5mm? Or are all ARP head bolts the same size, because I planned on using them.

bolts are 12mm but needed a little room to play with
