What kind of leak -- water, compression ??

If water did the studs have sealant applied to the threads going into the head since many locations are directly into the water jacket? Leakage must have been an ongoing issue because postwar they introduced special studs with different threads to better seal water leaks. The studs are not applicable and usable on earlier engines though. If there was sealant applied perhaps time or one of the coolant products for porous castings will take care of it.

If compression then I would wonder about damage to the gasket or a machined surface.
