If you don't need a lot of strength, what if you cross-thread the 3/8 hole with a tap for a 5/16 helicoil and add some filler like JB weld when you thread the helicoil in, maybe that would work? Kind of a cludge, but might be good enough?

For two reasons
1) Because I don't want to ruin the valuable 1970 original water pump
casting by drilling it's thru hole out to 3/8".
2) The judges check the heads and head markings on the water pump bolts.
These are indented head bolts which if you file down an indented 3/8 head,
the indent will disappear.
Do you think that not enough meat will be present in the casting to support
the threaded-insert?

Doug, since you seem to want to rescue this thing at any cost, why not take
the oversize 3/8" bolt and carefully file its hex down to a 5/16"-size. In
place, no judge will see the bolt threads or shank. Whatever, good luck- J
