I have these studs laying around for 2 years hoarding parts for rebuilt. Finally rebuilt is happening. I contacted ARP because I was missing tiny spec sheets. Above kit number is unknown on ARP's website (omit 'ARP-' prefix though). Kit was NOT delivered in ARP cardboard box as shown on this page.
ARP representative stated studs are NOT ARP. As aren't with my Head stud kit. Studs should have (laser) engraved number at the top. Mine don't, just 6 small indents around hex pattern at the top. Representative of ARP Racing Products stated torque specs therefor are unknown. Washers and nuts appears to be genuine though. I didn't pay for genuine washers and nuts. I paid for entire ARP kit. This page advertises selling ARP stud kit. I feel ripped of and in the contrary not feeling save. What the hell are these studs and what quality? No clue.
