You can go to ARP's site and get the length or i can measure a set tomorrow for you.
I just found a pic of where the adjuster should be.

From your pic, mine are way too low in the nut. These pushrods are Magnums as well....just a hair over 8 1/4" in length. Studs are stock, guide plates are COMP. Stock BBC heads.
ARP site says 3/8" should be 1.895 with roller rockers vs 1.750 stock length.
