I beleive these are the 2000 at least thats the closest I can come up with and they are 3/8 with 12pt. nuts, they also appear not to be the wave lok. The picture on the arp site site looks like the 2000. The rods are new 5140 I-beam, never got any paper with them as far as torque. As for torqueing them and leaving overnight thats a great idea. What about loctite on the final torque?
