Tim on intakes I have restored with similar issues I would first Tig weld the holes next step would be a slight resurfacing to make sure everything was flat and then tap the holes to the correct 5/16 coarse thread. Another way I have accomplished a repair without welding was with a step stud it is a bit more involved. The stud has a 3/8 coarse thread on one end and has a 5/16 thread on the other end. I make the step stud from a 3/8 bolt with a long shank that I then turn the shank to the 5/16 diameter so I can now thread it to the fine thread for the nut. Step studs I believe are available ready to use I just make them when needed so never took the time to source them. Using the step stud usually is the least amount of damage to a delicate and rare intake.
