Not trying to pile on here but, the Willys Jeep 134 engine has the same problem with the Best Gasket rear main seal leaking, they are made to big. One builder of the Jeep engines is now having his cranks welded oversize and ground to match the spec of the Best seal since the NOS supply has dried up.
