I think those are the ones I used when I built my 351W. The car is gone now, so I can't check. Those are the ones that crush a little to conform to the heads and headers for a better seal, right?
Another suggestion is use Stage 8 fasteners so your bolts don't loosen.
I had that car for 10 years and after one re-tightening after things settled in - I never had to touch them.
