Default ARP Bolt torque specs....

Ok, so finally got my bearings in the rods, now the torque specs are confusing me...
The sheet you get with the rods reads like this -

Bolt Identification Torque
7/16" ARP 8740 7/16 bolt head 63 ft lbs
7/16" ARP 2000 7/16 bolt head 75 ft lbs*
7/16" ARP L-19 1/2 bolt head 79 ft lbs
3/8" ARP 2000 7/16 bolt head 43 ft lbs*
5/16" ARP 2000 3/8 bolt head 28 ft lbs
5/16" ARP cutsom 3/8 bolt head 32 ft lbs

My bolts have a 7/16 head and have ARP 2000 stamped on the bolt head, so which torque specs do I use, as there are 2 choices (*)

Anyone help me out?

You need to measure the bolt size also.

I did this, it came out 9.3mm/0.36"

Does this mean its a 3/8" bolt? maths isnt my strong point!

3/8" is closest to your mesurement

3/8 is 0.3750" and 9.5250mm
7/16 is 0.4375" and 11.1125mm
