If the block is that bad, you would have to go to 3/8" helicoils/ then make special studs which were 3/8" in the block and 5/16" for the head. Is there enough metal in the block to do this as the O/d is about 0.468" for a BSF threaded helicoil. Because the diameter is increased, you could go BSF instead of traditional BSW in cast iron. Slightly smaller than 3/8 inserts would be to choose 8 or 8.5 mm ones.
It sounds like even the good holes would benefit from being helicoiled back to 5/16" BSW if you are going to this sort of trouble.
