Studs for Rocker Stands

[Michael C Henry]

I have a set of Dove heads.They resemble the originals,like most do. The studs are parallel and in a straight line.The rockers will lift off. They may have some drag but they will go on and lift off over the studs. As long as all the studs were installed in the original holes and not tipped or bent. Like someone tried to free hand drilling the head and got off a little. I had problems with the stud threads pulling out of head on the center two studs on both heads..My heads had already been converted to heli-coils. The center two studs pulled out coils and all. I Had to remove the heads and have a machinist do it in a machine to get the holes dead on. I had three styles of inserts and ended up with an insert that was 9/19x 18 outside and a little over a 1/2" long George Anderson at Guessford Machine said he had never repaired any Dove heads (which he deals in)But had repaired many Edelbrock heads. He uses a solid insert (Rock Mount) that is self threading . It takes a 33/64"drill and is 11/16" long.Every thing can be done in degrees .The original bolts are the start point, then coils , then inserts. The studs aren't the weak point the alluminum head is.You wont need a oversized stud but you'll have to do something with the head. The studs come coarse theads bottom to screw into the head as original but top is fine thread.They torque to 35 ftlbs with fine threads is a bunch.And get the ARP lube while youre at it.
