For 3/8" ARP 2000 rod bolts you want to do a stepped tq.

- Tq to 20lbs
- Tq to 35lbs
- Loosen

Repeat 3x holding at 40lbs on final tq.

This assumes you don't have a stretch gauge which is ideal. The reason you are doing it in steps is because it polishes the threads, giving you a more accurate tq reading.

I have no clue on the mains, IMO they are unneeded. The head stud tq looks good. You only need to hand thread them into the block. Just make sure the threads in the block are nice and clean and have been chased. If you cleaned the block off, like you should have, with soap and water. There is be some minor surface rust on the threads that needs to be cleaned off.

Also, don't skimp on the ARP lube! Use it on all surfaces touching metal to metal. Including under the head of the bolts, and on both sides of the washers. It is absolutely imperative in order to get an accurate tq reading. You will be very surprised to see how much additional you can turn the bolts after a few consecutive tq's. As the threads polish you will get an extra 1/4 turn at least out of the bolt when tq'ing to final tq.

There is a torque spec section in ARP's online catalog that goes off bolt or stud diameter. Try that, maybe it will get you in the ball park.
