Slant six manifold to head studs,13 total,where to obtain?

Does anybody sell these new,or will I have to post a parts wanted ad? I only need about 4 or 5. Thanks
I was able to answer my own question...Silver Seal Products in Michigan,50 cents each,$10.75 to ship 13.They are 1.88 inches long,OE was 1.75.That shouldn't be a problem.
