Plug kit for small block chevy. Install these plugs before painting to keep threads and freeze plugs clean of paint.

The plugs for bolt holes come in 3 different sizes

Small: 3/16"-1/8"
Medium: 3/16"-5/16"
Large: 3/8"-1/2"

I'm not sure if the freeze plug covers will work for other engines as the inside diameter of the freeze plug can very a lot. After printing I noticed that my hole expansion ratio settings were not correct. In this case, I have included the gcode files for it since I know that print file works for me.
