What size holes to drill?Zex direct port.

[AL92]

I got my Jm fab intake bungs for direct port nitrous.Be running a zex direct port.What size do I make the holes in the bungs and what size block off plugs do I need to fill them until I get the spray on the car likely next year.Figure its easier drilling the holes no before installation.
