Can I get single head studs anywhere?

[Vanspeed]

I bought a Snyder head long ago along with a new stud set and I sold the head a few years back and somehow I am missing one 3.5 stud and one of the front long 5 3/4 studs. I checked on arp’s site and the 5 3/4 stud only has 3/4 thread on the course end and the 3.5 inch has only fine thread on both ends. Does anybody know where I can get singles of the correct studs?
