Really enjoying this thread. What is your method of plugging the smog holes, drill tap and set screws? Are there any plugs that would be self tapping?

no drill, just 1/4 inch tap and 1/4 inch set screw. be sure to put a little oil on the tap and slowly cut back and forth so you don't break the tap off in the head.
