I went with longer, oversize studs when I re-restored my car. If it snapped off being tightened... you know what I mean? It's apparently standard practice on race cars, so I figured it's probably a good idea in general. It's not a really hard job-- you drift (pound!) the existing studs from the hub flanges, drill out the holes to the appropriate size and pound in the new ones. It might be a problem if you want to run the stock steel wheels and hubcaps-- the lug holes in the wheels might need to be drilled out and countersunk as well and the studs shortened to clear the hubcaps. I got mine from Winner's Circle in Ohio, but this was about 15 years ago. If you know the specs of the studs, a really good auto parts store can look'em up.
