When contacting bolt manufactures they will tell you that no bolt that is correct for our use is currently made. So prepare yourswelf for a lot of destroyed Fan cooled engines. When we were trying to get ARP to make them the problem became that you have to purchase large amounts of the meterial to produce a small run of bolts so the manufacture ends up stuck with a meterial that he doesn't have an immedialte use for. That creates a very high price for the bolt. The general public or manufacturing doesn't require a bolt that we need so it doesn't exist. Some will say use this bolt or that but at some point using a 180K bolt will mean you WILL pay the piper sooner or later. For now rebuilding fan cooled engines is dead unless you have an old stash.
