I have discontinued selling the 9/16" studs. They are expensive to begin with and it would be in the best interest of the customer to buy direct.
Alan Johnson (AJPE) 805-922-1202 offers 8.650 oal studs. They are quality 190,000 psi pieces with rolled threads and a female hex on top for installation. There is about .200 on the bottom that is not threaded to ensure the stud "bottoms" in the hole and does not bind on the partial threads. I talked with Richard Wilkinson at AJPE about the cost to shorten (10) of these 1/2″ on the block end (they come with 2" of thread). Richard went to the shop and was quoted 1 ½ hours of labor for (10) studs.
Please note: Prices may have changed since quote.
These studs are a little longer than a "stock" length stud (8 ½") but the top with the female hex is not threaded about .170 down so it comes out within .020.
NOTE: Standard height stands are: 2.060 on the intake side and 2.687 on the exhaust.
Keith Black also offers 8.750 & 9.260 oal stud that can be cut down to your specific length. It also has the .200 non-threaded protrusion on the bottom. The part number for these studs is 51287 and are $17.75. One of my customers indicated they fit his Titan setup.
For the unlimited budget, ARP has a 8.950 oal stud. This will accomodate any height stand as they have 2.400 of thread and can be cut off to fit. They are made of L19 material and can be yours for the paltry sum of $59.85 each.
Neither Titan or Donovan have 9/16″ studs for the early hemi.
