Vnet plug to controller - 16" 4. Power - 46"

Bung Installation

Bungs should be installed 8-12" form the flange 

O2 bungs are to be welded in a primary tube 8-12"from the cylinder head. Some racers get away with using one a collector but usually will experience choppy readings at lower RPM.	Click to expand

 Here is a link to a Vid showing where the guys with the unlimited budget put their O2 bungs https://www.youtube.com/watch?feature=player_embedded&v=p53oEbTGJkU#!

Below is a set of Pro-Fab headers with the bungs about 3" from the flange.
