Hello All
I am doing a custom build on a Ford Cologne 2.8L (74-79) and had one heck of a time finding header flanges ... so I designed/machined my own.
I designed them for 1 1/2" tubing (Hooker makes tubing and 3x inlet collectors) with a stop at the bottom which should afford good port matching and a positive stop for the tube to keep everything up tight.
I have fit them to the heads I have and everything seems to be OK but I will not be building the headers for several months (engine is not back from the machine shop). They are still a bit dirty so please excuse the big chunks.
Since I like sharing the resources, I am attaching the drawing files and a picture of the finished product.
As a side note: The drawings show a 'Z' drill for the bolt holes, however if one instead wishes a bit of a tighter tolerance might want to drill them using a 'Y' drill. The holes can always be opened up as needed.
Enjoy!
