Need to get thread chasers, need info asap. Thanks.

As the title states I am going to be getting some thread chasers for my block threads for the head studs, mains, and front case to block threads. I have read that the ones for my head studs are m12x1.25, is this correct? Just need to confirm. What about the thread for my mains and front case to block threads? I am going to an arp distributor in the morning and I would like to go ahead and get these from them as well. Thanks in advance.

Just for clarification I have a 1g 6 bolt.

for chasers just make your own, find some old bolts that fit, and take a cut off wheel and cut 3 grooves longways across the threads...
