Panhead rocker cover hole repair

Pretty common for guys to drill out the cover holes to 1/4" or heli coil the cover mount holes. Who ever did this one got a little carried away and drilled clear into the intake port. I threaded some aluminum 3/8" round stock, drilled and treaded the head. I welded it up at the top and die grinded the stub inside the port. Pretty easy fix and probably can be done with out the welding.
