There are 2 lengths used in the V-12 engine. Both of them carry a Ford P/N, so a Ford supplier like Southside Obsolete in MN, may have them. You could also check with an engine rebuilder to see if they know of a source. The studs are a grade  8.

 

Here are the P/N with description

48-6345 1/2" - 20 and 1/2"-13 threads over all length 3 -1/16"

 

68-6345 1/2" - 20 and 1/2"-13 threads over all length 3.30"
