Just something of note from Gill Welding and Fabrication
Yes, it was stated in the video. However they are working with Offy and they may be putting them out with the casting changed.The bungs have been welded onto the runners, the intake isn't cast with them on it....
For some views from Chrysler Engineering on that matter, see Figure 17 and the block of text below it on page 9 of this paper.But none of the intake based bungs have line of sight to the back of the valve.
