Here’s a pic of an ARP stud. The part number is on the box tab in the top right. ARP’s instructions included.

Overall length 6-3/4”.
Someone installed some that were a little longer (7”???- not sure) and they did interfere with the rocker assembly. They could be made to work (apparently), but...

From what I’ve heard the lube helps get more consistent torque.

Which is why I went to Summit Racing and bought a big container of the stuff. It's about the size of a container of anti-seize.
