5/16-18 x 1" Header Bolts Do They Exist?

Thanks guys.

Was looking at the ARP bolts but the guy at the speed shop said I might have to grind the shoulder a bit to fit. Looked the same as the header bolts to me.

70aarcuda, just what I was looking for, thanks. Tried to get them at the local speed shop, no good and nothing in there catalogs. Same for NAPA and another place. Came home and checked Summit, did Google search, ebay, but one place I did not check was Jegs.
