@math
Can you measure them? main studs are 10mm diameter and approx 95mm long.
7 bolt head studs are 11mm diameter and longer.
If the studs measure 12mm diameter they're for a 6 bolt.

 

[dsmotors95]

well i don't have a mm ruler but in length they are 4.5 inches which is 114.3mm

Main Studs are a 10mm ARP 207-5401 and torque 60 ft/lbs with ARP lube

6 bolt head studs are 12mm ARP 207-4201 And torque 90 ft/lbs

7 Bolt head studs are 11mm ARP 207-4203 and torque 80 ft/lbs

If you have main studs, they will not even thread in to a head bolt hole in the block, just fall in.

Main stud nuts use a 12pt x 12mm socket

6 bolt head stud nuts use a 12pt x 14mm socket

7 bolt head stud nuts use a 12pt x 13mm socket

Each kit will have
(10) studs
(10) washers
(10) nuts
(1) Pkg of ARP Ultra Moly lube (blue package)
