Here are some views of the headers that cant be seen while mounted inside the car.
Here is looking at the rear of the pipes showing the overlap.



Here is a top view.



Here is a view from the bottom. Notice how the LH side is closer to the block to clear the fuel tank shield. This was not planned its just how it turned out from fitting the pipes inside the car. You do not notice this from the top.



Here is a view from the bottom of the collectors showing more of the routing.



I start welding the flanges by turning the engine upside-down and welding the bottom.





Then I turn it over and weld the topsides.



I also finish welding the header collector tabs.



I take the headers off of the engine and mount them to the work table and finish off the ports with sanding rolls.
I take the same care that you would take on cylinder heads
